Recombinant Mouse Ciliary Neurotrophic Factor (Mouse CNTF)_C230532

Description

Ciliary neurotrophic factor (CNTF) is one of a small number of proteins with neurotrophic activities distinct from nerve growth factor (NGF). The cDNA for human CNTF encodes a 200 amino acid residue polypeptide that lacks a signal sequence. Recombinant human CNTF containing 200 amino acids and it shares 82% and 83% a.a. sequence identity with mouse and rat CNTF. The protein is a potent survival factor for neurons and oligodendrocytes and may be relevant in reducing tissue destruction during inflammatory attacks. In addition, CNTF is useful for treatment of motor neuron disease and it could reduce food intake without causing hunger or stress. CNTF is structurally related to IL-6, IL-11, LIF and OSM. Among factors belonging to the CNTF family, CNTF, leukemia inhibitory factor, cardiotrophin-1, and oncostatin M induced a strong promyelinating effect.

Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

>95% by SDS-PAGE and HPLC analyses.
Biological Activity

The ED50 as determined by a cell proliferation assay using human TF-1 cells is less than 30 ng/mL,
corresponding to a specific activity of > 3.3 × 10 4 IU/mg. 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 in 2 × PBS, pH 7.4, 2% trehalose.

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!
