  • Recombinant Human Complement Component C5a Protein _ C230316

    Recombinant Human Complement Component C5a Protein _ C230316

    Human Complement 5a (C5a) is an enzymatically generated glycoprotein that belongs to a family of structurally and functionally related proteins known as anaphylatoxins. C5a is a 74 amino acid (aa) peptide that is created by the activity of C5a convertase on the C5 alpha -chain. Human C5a has four alpha -helices plus three intrachain disulfide bonds that create a triple loop structure. In serum, proteolytic processing removes the Cterminal arginine, creating a low activity C5adesArg74 molecule. Human C5a is 60% and 54% aa identical to mouse and rat C5a, respectively. C5a binds to a signaling G-protein coupled receptor (C5aR/CD88) and a nonsignaling GPCR termed C5L2. Activation of Cd88 results in neutrophil chemotaxis and endothelial cell activation. It also triggers an oxidative burst in macrophages and neutrophils, and induces release of histamine in basophils and mast cells.

  • Recombinant Enhanced Green Fluorecence Protein ( eGFP)_C230274

    Recombinant Enhanced Green Fluorecence Protein ( eGFP)_C230274

    Botulinum and tetanus neurotoxins (BoNTs and TeNT) are zinc metalloproteases that hydrolyze and inactivate proteins necessary for neurotransmission. The protease domain is located in the light chain of the neurotoxin. Among the known substrates of BoNTs and TeNT are synaptosomal protein-25 (SNAP25) and vesicle-associated membrane protein (VAMP). This substrate incorporates a green fluorescent protein (GFPuv) and portions of human SNAP25B and VAMP2 that contain the cleavage sites of all the known BoNTs and TeNT. The light chains of BoNTs -A, -C, and -E cleave the SNAP25B sequence, while BoNTs -B, -D, -F, -G, and TeNT cleave within the VAMP2 sequence. The substrate can be used in a SDSPAGE gel-shift assay to detect cleavage by the neurotoxin proteases. Alternatively, the substrate can be coupled to maleimide-activated microwell plates through the C-terminal cysteine residue to generate a high throughput assay format. A similar substrate and assay format has been used to screen for inhibitors of these neurotoxin proteases.   Product Properties Synonyms Green Fluorecence Protein,GFP/SNAP25B/VAMP-2 Accession P42212 GeneID 7011691 Source E.coli-derived eGFP, with an N-terminal Met.

  • Recombinant Human Cardiotrophin-1 (Human CT-1) _C230314

    Recombinant Human Cardiotrophin-1 (Human CT-1) _C230314

    Cardiotrophin-1 (CT-1) is a member of the cytokine family which also includes IL-6, IL-11, leukemia inhibitory factor (LIF), oncostatin M (OSM), and ciliary neurotrophic factor (CNTF). It was originally isolated based on its ability to induce cardiac myocyte hypertrophy in vitro. CT-1 has since been shown to be a pleiotrophic cytokine with overlapping actions with other IL-6 family members on a variety of cell types. Human CT-1 encodes a 201 aa residue protein that lacks a hydrophobic signal peptide. The mechanism of CT-1 release from cells is currently not understood.

  • Recombinant Bovine bFGF/FGF-2 Protein_C230263

    Recombinant Bovine bFGF/FGF-2 Protein_C230263

    FGF basic is a member of the FGF family, currently comprised of seven related mitogenic proteins which show 35 - 55% amino acid conservation. FGF basic has been isolated from a number of sources, including neural tissue, pituitary, adrenal cortex, corpus luteum and placenta. This factor contains four cysteine residues but reduced FGF basic retains full biological activity, indicating that disulfide bonds are not required for this activity. Several reports indicate that a variety of forms of FGF basic are produced as a result of N-terminal extensions. These extensions apparently affect localization of FGF basic in cellular compartments but do not affect biological activity. Studies indicate that binding of FGF to heparin or cell surface heparan sulfate proteoglycans is necessary for binding of FGF to high affinity FGF receptors. FGF acidic and basic appear to bind to the same high affinity receptors and show a similar range of biological activities. FGF basic stimulates the proliferation of all cells of mesodermal origin, and many cells of neuroectodermal, ectodermal and endodermal origin. FGF basic is chemotactic and mitogenic for endothelial cells in vitro. FGF basic induces neuron differentiation, survival and regeneration. FGF basic has also been shown to be crucial in modulating embryonic development and differentiation. These observed in vitro functions of FGF basic suggest FGF basic may play a role in vivo in the modulation of such normal processes as angiogenesis, wound healing and tissue repair, embryonic development and differentiation, and neuronal function and neural degeneration.

  • Recombinant Equine Interferon-gamma ( Equine IFN-γ)_C230275

    Recombinant Equine Interferon-gamma ( Equine IFN-γ)_C230275

    IFN gamma, also known as IFNG, is a secreted protein that belongs to the type II interferon family. IFN gamma is produced predominantly by natural killer and natural killer T cells as part of the innate immune response, and by CD4 and CD8 cytotoxic T lymphocyte effector T cells once antigen-specific immunity develops. IFN gamma has antiviral, immunoregulatory, and anti-tumor properties. IFNG, in addition to having antiviral activity, has important immunoregulatory functions, it is a potent activator of macrophages and has antiproliferative effects on transformed cells and it can potentiate the antiviral and antitumor effects of the type I interferons. The IFNG monomer consists of a core of six α-helices and an extended unfolded sequence in the C-terminal region. IFN gamma is critical for innate and adaptive immunity against viral and intracellular bacterial infections and tumor control. Aberrant IFN gamma expression is associated with some autoinflammatory and autoimmune diseases. The importance of IFN gamma in the immune system stems in part from its ability to inhibit viral replication directly, and most importantly from its immunostimulatory and immunomodulatory effects. IFNG also promotes NK cell activity.   Product Properties Synonyms Interferon gamma;IFN-gamma; Accession P42160 GeneID 100034181 Source E.coli-derived equine Interferon-gamma protein,Gln24-Gln166 Molecular Weight Approximately 16.7 kDa.

    BAFF Receptor (BAFFR), a member of the TNFR superfamily, is highly expressed in the spleen, lymph nodes, and resting B cells, and to some extent in activated B cells, resting CD4+ cells and peripheral blood leukocytes. BAFFR is a type III transmembrane protein that binds with high specificity to BAFF (TNFSF13B).  BAFFR/BAFF signaling plays a critical role in B cell survival and maturation.  Human and mouse BAFF R share 56% aa sequence identity. BAFF R is highly expressed in spleen, lymph node and resting B cells. It is also expressed at lower levels in activated B cell, in resting CD4+ T cells, in thymus and peripheral blood leukocytes. BAFF knockout mice lack mature B cells. Similarly, A/WySnJ mice that are defective in BAFF-R intracellular signaling also lack mature B cells, suggesting that BAFF R is the critical receptor for BAFF during B lymphopoiesis. In contrast, BCMA- or TACI-deficient mice have no major defect in B-cell development. While the function of BCMA is not defined, TACI has been shown to control B-cell homeostasis and T-cell-independent immune responses.   Product Properties Synonyms BAFFR, TNFRSF13C Accession Q96RJ3 GeneID 115650 Source E.coli-derived Human B cell Activating Factor Rececptor protein,Met1-Gly76,with an N-terminal Met Molecular Weight Approximately 7.8 kDa AA Sequence MRRGPRSLRG RDAPAPTPCV PAECFDLLVR HCVACGLLRT PRPKPAGASS PAPRTALQPQ ESVGAGAGEA ALPLPG Tag None Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder.

  • Recombinant Equine Interleukin-1 beta ( Equine  IL-1β) _C230276

    Recombinant Equine Interleukin-1 beta ( Equine IL-1β) _C230276

    IL-1 is a name that designates two pleiotropic cytokines, IL-1 alpha (IL-1F1) and IL-1 beta (IL-1F2), which are the products of distinct genes. IL-1 alpha and IL-1 beta are structurally related polypeptides that share approximately 27% amino acid (aa) identity in equine. Both proteins are produced by a wide variety of cells in response to inflammatory agents, infections, or microbial endotoxins. While IL-1 alpha and IL-1 beta are regulated independently, they bind to the same receptor and exert identical biological effects. IL-1 RI binds directly to IL-1 alpha or IL-1 beta and then associates with IL-1R accessory protein (IL-1 R3/IL-1 R AcP) to form a high-affinity receptor complex that is competent for signal transduction. IL-1RII has high affinity for IL-1 beta but functions as a decoy receptor and negative regulator of IL-1 beta activity. IL-1ra functions as a competitive antagonist by preventing IL-1 alpha and IL-1 beta from interacting with IL-1 RI. The equine IL-1 beta cDNA encodes a 268 aa precursor. A 115 aa propeptide is cleaved intracellularly by the cysteine protease IL-1 beta -converting enzyme (Caspase-1/ICE) to generate the active cytokine. An alternatively spliced form of equine IL-1 beta has a deletion which encompasses the Caspase-1 cleavage site and potentially results in a membrane-associated form. The 17 kDa mature equine IL-1 beta shares 65%-75% aa sequence identity with canine, cotton rat, feline, human, mouse, porcine, rat, and rhesus IL-1 beta.   Product Properties Synonyms IL-1 beta Accession Q28386 GeneID 100034237 Source E.coli-derived Equine IL-1β, Ala116-Ala268.

  • Recombinant Human Interleukin-1 Receptor Antagonist Protein (Human IL-1RA)_ C230385

    Recombinant Human Interleukin-1 Receptor Antagonist Protein (Human IL-1RA)_ C230385

    IL-1ra was originally isolated from the urine of patients with monocytic leukemia and has also been purified from adherent monocytes. The naturally occurring, fully glycosylated form has an apparent molecular weight of about 25,000 Daltons. The protein shows 26% amino acid homology to IL-1 beta and 19% homology to IL-1 alpha. It will compete with either factor for receptor binding, but does not interact with either one. Human IL-1ra will bind to both types of IL-1 receptor (I and II) on human cells, but reportedly will not block binding to the type II receptor on murine pre-B cell lines. The recombinant, non-glycosylated form of IL-1ra blocks binding of IL-1 to its receptor equally as well as the naturally-occurring, glycosylated form. The IL-1ra has been shown to block the inflammatory responses induced by IL-1 both in vitro and in vivo. Currently, pre-clinical and clinical studies are underway to test possible therapeutic applications for IL-1ra in the treatment of sepsis, rheumatoid arthritis and chronic myelogenous leukemia.   Product Properties   Synonyms IL-1RN, IRAP Source E.coli-derived Human IL-1RA, Arg26-Glu177.

    Interleukin-5 (IL-5) is a secreted glycoprotein that belongs to the alpha -helical group of cytokines. Unlike other family members, it is present as a covalently linked antiparallel dimer. The cDNA for human IL-5 encodes a signal peptide and a 115 amino acid (aa) mature protein. Mature human IL-5 shares 70%, 70%, 62%, 71%, 70% and 66%, aa sequence identity with mouse, rat, canine, equine, feline and porcine IL-5, respectively and shows cross-reactivity with mouse IL-5. IL-5 is primarily produced by CD4+ Th2 cells, but also by activated eosinophils, mast cells, EBV-transformed B cells, Reed-Sternberg cells in Hodgkin’s disease, and IL- 2-stimulated invariant natural killer T cells (iNKT). IL-5 increases production and mobilization of eosinophils and CD34+ progenitors from the bone marrow and causes maturation of eosinophil precursors outside the bone marrow. The receptor for human IL-5, mainly expressed by eosinophils, but also found on basophils and mast cells, consists of a unique ligand-binding subunit (IL-5 R alpha ) and a shared signal-transducing subunit, beta. IL-5 R alpha first binds IL-5 at low affinity, then associates with preformed beta c dimers, forming a high-affinity receptor.   Product Properties   Synonyms B-cell differentiation factor I, Eosinophil differentiation factor, TRF Source E.coli-derived human IL-5 protein, Ile20-Ser134,with an N-terminal Met.

    Recombinant Human Interleukin-17B (Human IL-17B)_ C230392

    The Interleukin 17B (IL-17) family proteins, comprising six members (IL-17, IL-17B through IL-17F), are secreted, structurally related proteins that share a conserved cystine-knot fold near the C-terminus, but have considerable sequence divergence at the N-terminus (1, 2). With the exception of IL-17B, which exists as a non- covalently linked dimer, all IL-17 family members are disulfide-linked dimers (3). IL-17 family proteins are pro-inflammatory cytokines that induce local cytokine production and are involved in the regulation of immune functions (1, 2). Two receptors (IL- 17 R, and IL-17B R), which are activated by IL-17 family members, have been identified. In addition, at least three additional orphan type I transmembrane receptors with homology to IL-17 R, including IL-17 RL (IL-17 RC), IL-17 RD, and IL- 17 RE, have also been reported (1- 4). Human IL-17B cDNA encodes a 180 aa protein with a putative 20 aa signal peptide (5, 6). Human and mouse IL-17B share 88% amino acid sequence identity. Among IL-17 family members, IL-17B is most closely related to IL-17D, sharing 27% aa sequence homology. IL-17B is expressed highly in spinal cord, and at lower levels in brain, kidney, lung, small intestine, prostate, testes, pancreas, adrenal gland and trachea (5- 7). Expression of IL-17B has also been detected in chondrocytes in articular cartilage (2). IL-17B binds the IL-17B receptor but not IL-17 R and exhibits bioactivities distinct from those of IL-17 (5, 6).   Product Properties   Synonyms IL-17B Source E.coli-derived human IL-17B protein, Gln21-Phe180, with an N-terminal Met.

  • Recombinant Human Interleukin-20 (Human IL-20)_ C230397

    Recombinant Human Interleukin-20 (Human IL-20)_ C230397

    IL-20 belongs to the IL-10 family. It is a cytokine structurally related to interleukin 10. Human IL-20 is synthesized as a 176 amino acid (aa) precursor with a 24 aa signal sequence and a 152 aa mature segment. IL-20 production has been found in skin, trachea, and other tissues. In particular, it is produced by activated keratinocytes and monocytes. It has been shown that IL-20 transduces its signal through signal transducer and activator of transcription 3 (STAT3) in keratinocytes. It may be involved in epidermal function and psoriasis. It also regulates the proliferation and differentiation of keratinocytes during inflammation, particularly inflammation associated with the skin. Also, it is reported to induce the proliferation of multipotential hematopoietic progenitor cells, direct the differentiation and expansion of keratinocytes, and promote the release of proinflammatory mediators in keratinocytes and other IL-20 receptor expressing cells.   Product Properties   Synonyms Cytokine Zcyto10 Source E.coli-derived Human IL-20, Leu25-Glu176, with an N-terminal Met.

  • Recombinant Human IL-22 Protein_ C230399

    Recombinant Human IL-22 Protein_ C230399

    Interleukin-22 (IL-22), also known as IL-10-related T cell-derived inducible factor (IL-TIF) was initially identified as a gene induced by IL-9 in mouse T cells and mast cells. Human IL-22 cDNA encodes a 179 amino acid (aa) residue protein with a putative 33 aa signal peptide that is cleaved to generate a 147 aa mature protein that shares approximately 79% and 22% aa sequence identity with mouse IL-22 and human IL-10, respectively. The human IL-22 gene is localized to chromosome 12q15. Although it exists as a single copy gene in human and in many mouse strains, the mouse IL-22 gene is duplicated in some mouse strains including C57B1/6, FVB and 129. The two mouse genes designated IL-TIF alpha and IL-TIF beta, share greater than 98% sequence homology in their coding region. IL-22 has been shown to activate STAT- 1 and STAT-3 in several hepatoma cell lines and upregulate the production of acute phase proteins. IL-22 is produced by normal T cells upon anti-CD3 stimulation in humans. Mouse IL-22 expression is also induced in various organs upon lipopolysaccharide injection, suggesting that IL-22 may be involved in inflammatory responses. The functional IL-22 receptor complex consists of two receptor subunits, IL-22R (previously an orphan receptor named CRF2-9) and IL-10R beta (previously known as CRF2-4), belonging to the class II cytokine receptor family.   Product Properties   Synonyms Cytokine Zcyto 18, TIF Source E.coli-derived human IL-22 protein, Ala34-Ile179.

    Recombinant Human Interleukin-36 alpha, 158aa (Human IL-36α, 158aa)_ C230404

    Human IL-36 alpha, previously called IL-1F6 and FIL1 epsilon (family of IL-1 member epsilon), is a member of the IL-1 family which includes IL-1 beta, IL-1 alpha, IL-1ra, IL-18, and novel family members IL-36 Ra (IL-1F5), IL-36 beta (IL-1F8), IL-36 gamma (IL-1F9), IL-37 (IL-1F7) and IL- 38 (IL- 1F10) . All family members show a 12 beta -strand, beta -trefoil configuration, and are believed to have arisen from a common ancestral gene. IL-36 alpha is an 18- 22 kDa, 158 amino acid (aa) intracellular and secreted protein that contains no signal sequence, no prosegment and no potential from N-linked glycosylation sites. It can be released in response to LPS and the cell ATP-induced activation of the P2X7 receptor. A 120 aa isoform missing aa 1- 38 has been reported. Human IL- 36 alpha (aa 6 - 158) shares 57- 68% aa sequence identity with mouse, rabbit, equine and bovine IL- 36 alpha and 27- 57% aa sequence identity with other novel IL- 1 family members. IL- 36 alpha is mainly found in skin and lymphoid  tissues, but also in fetal brain, trachea, stomach and intestine. It is expressed by monocytes, B and T cells. The receptor for IL- 36 alpha is a combination of IL- 1 Rrp2 (also called IL1RL2 or IL- 1 R6), mainly found in epithelia and keratinocytes, and the widely expressed IL- 1 RAcP. IL-36 alpha, beta, and gamma all activate NF-kappa B and MAPK pathways in an IL- 1 Rrp2 dependent manner, and induce production of inflammatory cytokines and chemokines such as CXCL8/IL-8. IL-36 alpha and other family members are overexpressed in psoriatic skin lesions, and transgenic overexpression of IL- 36 alpha in skin keratinocytes produces epidermal hyperplasia. IL-36 alpha is present in kidney tubule epithelia, and it is highly expressed in intubulointerstitial lesions in mouse models of chronic glomerulonephritis, lupus nephritis and diabetic nephritis.

  • Recombinant Human Interleukin-36 gamma, 152aa (Human IL-36γ,152aa)_ C230407

    Recombinant Human Interleukin-36 gamma, 152aa (Human IL-36γ,152aa)_ C230407

    IL-36 gamma [previously called IL-1F9, IL-1 epsilon (epsilon), and IL-1H1] is a member of the IL-1 family which includes IL- 1 beta, IL- 1 alpha, IL- 1ra, IL- 18, IL- 36 Ra (IL- 1F5), IL-36 alpha (IL- 1F6), IL- 36 beta (IL- 1F8), IL- 37 (IL- 1F7) and IL-1F10. All family members show a 12 beta -strand, beta -trefoil configuration, and are believed to have arisen from a common ancestral gene. IL- 36 gamma is an 18- 22 kDa, 169 amino acid intracellular and secreted protein that contains no signal sequence, no prosegment and no potential N-linked glycosylation sites. Human IL- 36 gamma (aa 18- 169) shares 58%, 59%, 68% and 69% aa sequence identity with mouse, rat, bovine and equine IL- 36 gamma, respectively, and 23- 57% aa sequence identity with other family members. 134 aa isoform missing aa 19- 53 has been reported. Highest levels of IL- 36 gamma are produced by Langerhans cells, keratinocytes, and stomach Chief cells and parietal cells; these cells contribute to first-line defense against pathogens in the skin, lungs and  digestive tract. Its expression is induced by LPS treatment of monocytes, and by IL- alpha / beta, IL- 17 or TNF- alpha treatment of keratinocytes and bronchial epithelia. Skin IL-36 gamma expression is increased in contact hypersensitivity and psoriasis. It is elevated in inflammatory disorders of the lung (such as asthma) and viral infections. Lung IL- 36 gamma and other IL- 36 proteins contribute to neutrophil influx. The receptor for IL-36 gamma is a combination of IL- 1 Rrp2, mainly found in epithelia and keratinocytes, and the widely expressed IL- 1 RAcP. IL- 36 alpha,beta and gamma all activate NF- kappa B and MAPK pathways in an IL- 1 Rrp2 dependent manner, and IL- 36 gamma induces production of inflammatory cytokines and chemokines such as CXCL8/IL- 8.

  • Recombinant Human Interleukin-36 Receptor Antagonist Protein (Human IL-36RA)_ C230409

    Recombinant Human Interleukin-36 Receptor Antagonist Protein (Human IL-36RA)_ C230409

    Human interleukin-36 receptor antagonist IL-36Ra; previously IL-1F5 and also named FIL-1δ (delta), IL- 1HY1, IL- 1H3, and IL-1L1 is a member of the IL- 1 family of proteins. IL- 1 family members include IL-1 beta, IL-1 alpha, IL-1ra, IL- 18 and IL-1F5-F10. All family members show a 12 beta -strand, beta -trefoil configuration, and all family members are believed to have arisen from a common ancestral gene that underwent multiple duplications . The human IL- 36Ra/IL- 1F5 gene is in closest proximity to the gene for IL-1ra and is likely a relatively recent duplication of the IL-1ra gene. IL-36Ra/IL-1F5 is synthesized as a 155 amino acid (aa) protein that contains no signal sequence, no prosegment and no potential N-linked glycosylation site(s). Nevertheless, it appears to be secreted as a 17 kDa monomer. There is an alternate start site that potentially gives rise to an alternate splice form. The translated product, however, has a premature stop codon, resulting in a truncated 16 aa peptide. Human to mouse, full length IL-1F5 has 90% aa identity. Within the family, IL-36Ra/IL-1F5 is 50% aa identical to IL-1ra, and 32%, 31%, 35%, 37%, 32% and 42% aa identical to IL-1 beta, IL-36 alpha /IL- 1F6, IL- 37/IL- 1F7, IL- 36 beta /IL- 1F8, IL- 36 gamma /IL- 1F9 and IL- 1F10, respectively. Cells reported to expressIL- 36Ra/IL- 1F5 include monocytes, B cells, dendritic cells/Langerhans cells, keratinocytes, and gastric fundus Parietal and Chief cells. The receptor for IL-36Ra/IL-1F5 has not been positively identified. Indirect evidence suggests it is IL-1 Rrp2 and/or IL-1 RAcP. In either case, activity association with receptor binding is also unclear. It was initially reported to be an antagonist of IL- 36 gamma /IL- 1F9 activity. This would be consistent with its hypothesized relationship to IL- 1ra. Studies, however, find IL-36Ra/IL-1F5 antagonist activity difficult to demonstrate.
