Other Performance Data: Endotoxin Level: Measured by kinetic LAL analysis and is typically ≤ 1 EU/μg protein. Biologic Activity: The activity is determined by the dose-dependent proliferation of mouse BALB/c 3T3 cells and is typically 2.0 ng/mL.
Physical State: Lyophilized
Purity and Specificity: Fibroblast Growth Factor acidic purity was determined to be greater than 97% as determined by analysis by UV-Spectroscopy at 280nm and by reducing and non-reducing SDS-pAGE.
Background: Fibroblast Growth Factors (FGFs) are a 22 member family of proteins known to be involved in angiogenesis, wound healing and embryonic development. As a family, they bind to heparin and signal through four receptor tyrosine kinases called, FGFR1, 2, 3 and 4. FGF-acidic, or FGF-1, is a particularly potent inducer of DNA synthesis and has chemotactic activities. Recombinant human FGF acidic is a non-glycosylated protein, containing 141 amino acids, with a molecular weight of 16 kDa.
Low Endotoxin: Yes
