BP000029-GD3: Recombinant Human FGF Acidic 136 (aa 19-155) Protein
Source: E. coli-derived.
The FGF acidic (aFGF/FGF-1/FGF1) activity is measured in a NIH/3T3 cell proliferation assay. The ED50 for this effect is typically 0.1-0.3 ng/ml in the presence of 10 ug/ml of heparin.
Endotoxin: <1.0 EU per 1 ug of the protein by the LAL method.
Purity: > 95% by SDS-PAGE under reducing conditions and visualized by silver stain.BP000029-C043: Recombinant Mouse Fibroblast Growth Factor 1 (FGF-1) Protein
Source: E. coli-derived.
The specific activity of Recombinant Mouse Fibroblast Growth Factor 1 (FGF-1) Protein is calculated by its ability to 2.0 x 106 IU/mg. The ED50 for this effect is typically less than 0.5 ng/ml as determined by the dose-dependent stimulation of thymidine uptake by 3T3 cells in the presence of Heparin.
Purity: >95% by SEC-HPLC and reducing SDS-PAGE.
Endotoxin: < 0.1 ng/ug (1 IEU/ug).
