Technical Data
Ciliary Neurotropic Factor, Recombinant, Rat (CNTF)
Molecular Biology Storage: -20CShipping: Blue Ice
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. CNTF is a survival factor for various neuronal cell types and seems to prevent the degeneration of motor axons after axotomy. CNTF Recombinant Rat produced in E. coli is a single, non-glycosylated polypeptide chain containing 200aa and having a molecular mass of 22834D. The CNTF is purified by proprietary chromatographic techniques.
