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.
Product Details
- Target Species
- Human
- Product Form
- Purified recombinant protein - lyophilized
- Reconstitution
- 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.

Storage Information
- Storage
- Prior to reconstitution store at -20oC.
After reconstitution store at -20oC.
Storage in frost-free freezers is not recommended. This product should be stored undiluted. Avoid repeated freezing and thawing as this may denature the antibody. Should this product contain a precipitate we recommend microcentrifugation before use. - Guarantee
- Guaranteed for 3 months from the date of reconstitution or until the date of expiry, whichever comes first. Please see label for expiry date.
