> 95% as determined by (a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
Activity:
ED50 <0.5 ng/mL, measured by the dose-dependant proliferation of mouse BALB/c 3T3 cells, corresponding to a specific activity >2 x 106?IU/mg.
Storage Buffer:
Lyophilized from a solution containing 1X PBS, pH7.4. Reconstitute the lyophilized powder in ddH2O to 0.1mg-0.25mg/mL. Allow sample to sit for 5 min at 4 °C, spin to remove precipitant.
Storage Instruction:
Stored at 4°C for 2-4 weeks, should be stored at -20°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid repeated freeze/thaw cycles.
The protein encoded by this gene is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. This protein functions as a modifier of endothelial cell migration and proliferation, as well as an angiogenic factor. It acts as a mitogen for a variety of mesoderm- and neuroectoderm-derived cells in vitro, thus is thought to be involved in organogenesis. Multiple alternatively spliced variants encoding different isoforms have been described. [provided by RefSeq
