FGF 4 (fibroblast growth factor 4) is a member of the heparin-binding growth factors family which act as promoters of cellular differentiation and proliferation, and therefore play key roles in embryonic development, morphogenesis, tissue regeneration and tumour growth and invasion. Studies have shown that FGF 4 signals through binding to the FGF Receptors (FGFRs) 1c, 2c, 3c, and 4.
Purified recombinant protein - lyophilised
Reconstitute with 250ul distilled water Care should be taken during reconstitution as the protein may appear as a film at the bottom of the vial. Bio-Rad recommend that the vial is gently mixed after reconstitution.
Purified recombinant FGF 4 expressed in E.coli
The ED50 as determined by the dose-dependent stimulation of thymidine uptake by BaF3 cells expressing FGF-receptors is ≤ 0.5 ng/ml, corresponding to a specific activity of ≥ 2 x 106 units/mg.
