Description
FGF basic, also known as FGF-2 and HBGF-2, is a member of the FGF superfamily of mitogenic proteins which show 35-60% amino acid conservation. Human FGF acidic shares 54% amino acid (aa) sequence identity with FGF basic and 17%-33% with other human FGFs. It shares 92%, 96%, 96%, and 96% aa sequence identity with bovine, mouse, porcine, and rat FGF acidic, respectively, andexhibits considerable species crossreactivity. Alternate splicing generates a truncated isoform of human FGF acidic that consists of the Nterminal 40% of themolecule and functions as a receptor antagonist. The effects of androgen and FGF-2 could be partly reversed with a specific anti-FGF-2 immunoglobulin G or by suramin, which inhibits binding of FGFs to their high affinity receptors. Additionally, bFGF is frequently used for a critical component of cell culture medium, human embryonic stem cell culture medium, serum-free culture systems.

Reconstitution |
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20℃. Further dilutions should be made in appropriate buffered solutions. |
Shipping and Storage
The products are shipped with ice pack and can be stored at -20℃ for 1 year.
1 month, 2 to 8 °C under sterile conditions after reconstitution.
3 months, -20 °C under sterile conditions after reconstitution.
Recommend to aliquot the protein into smaller quantities when first used and avoid repeated freeze-thaw cycles.
Cautions
