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%-_x005f33% 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, e.g., human embryonic stem cell culture medium, serum-free culture systems.

Approximately 16.5 kDa.

Sterile Filtered White lyophilized (freeze-dried) powder.

>98% by SDS-PAGE and HPLC analyses.

The ED50 as determined by a cell proliferation assay using murine balb/c 3T3 cells is less than 1.0 ng/mL, corresponding to a specific activity of > 1.0 × 106 IU/mg. Fully biologically active when compared to standard.

< 1.0 EU per 1μg of the protein by the LAL method.

Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4.

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.
