Description
CNTF Human Recombinant produced in E.Coli is a single,
non-glycosylated polypeptide chain containing 220 amino acids (1-200 a.a) and
having a molecular mass of 25kDa. CNTF is fused to a 20 amino acid His-tag at N-terminus
& purified by proprietary chromatographic techniques.
Synonyms
Ciliary neurotrophic factor, CNTF, HCNTF.
Introduction
CNTF is a polypeptide hormone whose actions appear to be restricted to the nervous system where it promotes neurotransmitter synthesis and neurite outgrowth in certain neuronal populations. The protein is a potent survival factor for neurons and oligodendrocytes and may be relevant in reducing tissue destruction during inflammatory attacks. A mutation in this gene, which results in aberrant splicing, leads to ciliary neurotrophic factor deficiency, but this phenotype is not causally related to neurologic disease. In addition to the predominant monocistronic transcript originating from this locus, the gene is also co-transcribed with the upstream ZFP91 gene. Co-transcription from the two loci results in a transcript that contains a complete coding region for the zinc finger protein but lacks a complete coding region for ciliary neurotrophic factor. CNTF is a survival factor for various neuronal cell types. Seems to prevent the degeneration of motor axons after axotomy.
Physical Appearance
Sterile Filtered clear solution.
Formulation
CNTF protein solution (1mg/ml) containing 20 mM Tris-HCl
buffer (pH 8.5), 1 mM DTT,30% Glycerol and 0.2M NaCl.
Solubility
/
Stability
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid multiple freeze-thaw cycles.
Purity
Greater than 95.0% as determined by SDS-PAGE.
Biological Activity
Measured in a cell proliferation assay using TF-1 human erythroleukemic cell. The ED50 for this effects is less
or equal to 1 ug/ml.
