Recombinant Human CNTF is a 199 amino acid, Escherichia coli-derived recombinant protein corresponding to mature human ciliary neutotrophic factor (CTNF), a survival factor for various neuronal cell types believed to prevent the degeneration of motor axons after axotomy.
- Target Species
- Product Form
- Purified recombinant protein - lyophilized
- Reconstitute with 0.2 ml distilled water. Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. Bio-Rad recommend that the vial is gently mixed after reconstitution. For extended storage, the addition of 0.1% bovine serum albumin (BSA) is recommended.
- Purified recombinant CTNF expressed in E. Coli
- Buffer Solution
- 10mM Citric Acid + 75mM NaCl
- Preservative Stabilisers
- None present
- Carrier Free
- The ED50 as determined by the dose-dependent proliferation of human TF-1 cells is 50-150ng/ml.
- >98% by SDS PAGE/HPLC
- Approx. Protein Concentrations
- 0.1 mg/ml after reconstitution
- Protein Molecular Weight
- 22.7 kDa
- Endotoxin Level
