Predicted Species Reactivity | Human |
---|---|
Product Format | Lyophilized from a concentrated (1mg/ml) solution in water containing 5mM sodium Phosphate buffer pH=7.5 and 5mM sodium chloride. Physical appearance: Sterile Filtered White lyophilized (freeze-dried) powder. |
Host | E. Coli |
Additional Information | Solubility: It is recommended to reconstitute the lyophilized HCNTF in sterile 18M Omega -cm H2O not less than 100 ug/ml, which can then be further diluted to other aqueous solutions. |
:: | Biological Activity: The ED50 as determined by the dose-dependant stimulation of TF-1 cells is < 2 ng/ml, corresponding to a Specific Activity of 5 x 105 IU/mg. |
:: | Protein Content: CNTF quantitation was carried out by two independent methods1. UV spectroscopy at 280 nm using the absorbency value of 1.28 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics). 2. Analysis by RP-HPLC, using a standard solution of CNTF Recombinant as a Reference Standard. Protein Content: CNTF quantitation was carried out by two independent methods1.

:: | Product 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. Product Description: Ciliary Neurotrophic Factor Recombinant Human produced in E.Coli is a single, non-glycosylated polypeptide chain containing 199 amino acids and having a molecular mass of 22706 Dalton. The CNTF is purified by proprietary chromatographic techniques. |
Reconstitution and Storage | Lyophilized Ciliary Neurotrophic Factor although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution CNTF should be stored at 4C between 2-7 days and for future use below -18C. Please prevent freeze-thaw cycles. |
Purity | Greater than 98.0% as determined by (a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE. |
Peptide Sequence | The sequence of the first five N - terminal amino acids was determined and was found to be Met - Ala - Phe - Thr - Glu. |
