Recombinant human FGF-basic (bFGF) (AA 1-154), also called as FGF-2 or FGFb, is a bioactive protein intended for use in cell culture applications. bFGF is a heparin-binding member of the FGF superfamily of molecules. It is involved in a number of biological processes including embryonic development, differentiation, survival, regeneration and migration. In addition, bFGF is a critical factor for growing embryonic stem cells in culture to remain cell in an undifferentiated state. |
Source: | Escherichia Coli. |
Purity: |
Greater than 98%, as determined by SDS-PAGE (See SDS-PAGE Image)
|
Endotoxin: | Less than 0.01 ng/ug cytokine as determined by the LAL assay |
Bioactivity: | ED50= 0.1-0.3 ng/ml as determined by the dose dependent proliferation of NIH 3T3 cells. |
Formulation: | Sterile filtered and lyophilized from Tris buffer (10 mM Tris pH7.5, 150 mM NaCl). |
Reconstitution: | Centrifuge vial before opening. It is recommended to reconstitute bFGF in sterile 10 mM Tris-HCl, pH7.5 to yield a stock solution of 0.1 mg/ml of bFGF. It is stable for up to 6 months when stored at -20°C and up to 12 months when stored at -80°C. Multiple freeze/thaw cycles will result in significant loss of activity. |
NIH/3T3 cells (mouse fibroblast cell line, ATCC: CCL-1668) were cultured in the absence of bFGF. |
NIH/3T3 cells were cultured with 0.25 ng/ml bFGF in serum-free medium at 37°C, 5% CO2 for 24 hours. |
