Recombinant Human Chemokine-like protein TAFA-2 (Human TAFA-2) _C230315

Description

TAFA2 also named FAM19A2, is a secreted, 11 kDa member of the FAM19/TAFA family of chemokine-like proteins. It is synthesized as a 131 amino acid (aa) precursor that contains a 30 aa signal sequence and a 101 aa mature chain. Like other members of the FAM19/TAFA family, with the exception of TAFA5, mature TAFA1 contains 10 regularly spaced cysteine residues that follow the pattern CX7CCX13CXCX14CX11CX4CX5CX10C, where C represents a conserved cysteine residue and X represents any noncysteine amino acid. Human TAFA2 is 97% aa identical to mouse TAFA2. The biological functions of TAFA family members remain to be determined, but there are a few tentative hypotheses. First, TAFAs may modulate immune responses in the CNS by functioning as brain-specific chemokines, and may act with other chemokines to optimize the recruitment and activity of immune cells in the CNS. Second, TAFAs may represent a novel class of neurokines that act as regulators of immune nervous cells. Finally, TAFAs may control axonal sprouting following brain injury.

Tag

None

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

>95% by SDS-PAGE and HPLC analyses.

Biological Activity

The biological activity is determined by its ability to enhance neurite outgrowth of E16-E18 rat embryonic cortical neurons. recombinant human TAFA-2, immobilized at 6-24 μg/mL on a 96 well plate, is able to significantly enhance neurite outgrowth. Fully biologically active when compared to standard.

Endotoxin

< 1.0 EU per 1μg of the protein by the LAL method.

Formulation

Lyophilized from a 0.2 μm filtered concentrated solution in 2 × PBS, pH 7.4.

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20. Further dilutions should be made in appropriate buffered solutions.

 

Shipping and Storage

The products are shipped with ice pack and can be stored at -20℃ to -80℃ for 1 year.

 

Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.

 

Cautions

1. Avoid repeated freeze-thaw cycles.

2. For your safety and health, please wear lab coats and disposable gloves for operation.

3. For research use only!
