Products from BPS Bioscience require a minimum order value above 400€
Encompassing Amino Acids: 134 - 288
Application: Useful for cell culture and for the study of signaling pathways.
Biological Activity: The ED50 was determined by the dose-dependent stimulation of thymidine uptake by BaF3 cells expressing FGF receptors, corresponding to a specific activity of ≥ 2x 106 units/mg.
Description: Recombinant human soluble basic FGF (GenBank Accession No. NM_002006) is a 17.3 kDa (134 aa-288 aa) protein expressed in an E. coli expression system.
Endotoxin Level: < 1EU per ug of bFGF as determined by the LAL method.
Format: lyophilized protein
Formulation: Lyophilized from a 0.2 µm filtered solution containing 1M NaCl and 20 mM Phosphate buffer, pH 7.
Genbank: NM_002006
