FGF-basic 154: Human Fibroblast Growth Factor 154 basic |
 |
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. Although the mechanism remains unclear, FGF-basic 154 (known as FGF basic) is a critical component in keeping embryonic stem cells undifferentiated in cell culture systems.
Recombinant human FGF-b 154 (FGF-2) is a non-glycosylated protein, containing 154 amino acids and having a molecular mass of 17.2 kDa.
Products are for research use only. They are not intended for human, animal, or diagnostic applications.

Cat. No.:
RP1146
Alternative Name:
FGF2, HBGF-2, Prostatropin
Source:
E. coli
Physical Appearance:
Sterile Filtered white lyophilized (freeze-dried) powder.
Formulation:
Recombinant human FGF-b 154 is lyophilized from a 10 mM sodium phosphophate buffer, pH 8.0.
Stability:
Lyophilized product is very stable at -20°C. Reconstituted material should be aliquoted and frozen at -20°C. It is recommended that a carrier protein (0.1% HSA or BSA) is added for long term storage.
Reconstitution:
Centrifuge vial before opening. When reconstituting the product, gently pipet and wash down the sides of the vial to ensure full recovery of the protein into solution. It is recommended to reconstitute the lyophilized product with sterile water at a concentration of 0.1 mg/ml, which can be further diluted into other aqueous solutions.
Protein Content and Purity determined by:
UV spectroscopy at 280 nm.
RP-HPLC calibrated against a known standard.
Quantitation against a known standard via reducing and non-reducing SDS-PAGE gels.
RP-HPLC calibrated against a known standard.
Quantitation against a known standard via reducing and non-reducing SDS-PAGE gels.
Endotoxin Level:
Endotoxin level, as measured by LAL analysis, is <0.01ng/ug or <0.1EU/ug.
Biological Activity:
The activity is calculated by the dose-dependent proliferation of mouse BALB/c 3T3 cells and is typically less than 1 ng/ml.
