Recombinant Human FGF basic represents the C-terminal protion of human fibroblast growth factor 2 (A135 - S288).

Fibroblast growth factor basic (FGF basic), also known as FGF 2, is a heparin binding growth factor which has stimulatory activity on a range of cells of mesenchymal, neuroectodermal and endothelial origin.
Note: FGF basic is sensitive to acidic conditions.

Target Species
Human
Product Form

Reconstitution
Reconstitute with 0.5 ml Tris (5mM, pH7.6).
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. Further dilutions may be prepared in a buffer containing a carrier protein (eg 0.1% BSA).
Buffer Solution
TRIS buffered saline.
Preservative Stabilisers
None present
Carrier Free
Yes
Activity
2 x 106 units/mg
Purity
>95% by SDS PAGE and HPLC analysis
Approx. Protein Concentrations
Total protein concentration 0.1 mg/ml after reconstitution.
Protein Molecular Weight
17.2 kD (154 amino acid sequence)
Endotoxin Level
< 0.1 ng/ug
Regulatory
For research purposes only
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.

Prior to reconstitution store at -20oC. Following reconstitution store at -20oC.

This product should be stored undiluted.

Storage in frost-free freezers is not recommended. Avoid repeated freezing and thawing as this may denature the protein. Should this product contain a precipitate we recommend microcentrifugation before use.

This product has been reported to work in the following applications. This information is derived from testing within our laboratories, peer-reviewed publications or personal communications from the originators. Please refer to references indicated for further information. For general protocol recommendations, please visit the antibody protocols page.
