Fibroblast Growth Factor 4, Recombinant, Human (FGF-4, Heparin Secretory Transforming Protein 1, HSTF-1, HST-1, HST, Transforming Protein KS3, Heparin-binding Growth Factor 4, HBGF-4, HSTF1, KS3)

FGF4 is a heparin binding growth factor that is a member of the FGF family. Proteins of this family play a central role during prenatal development and postnatal growth and regeneration of a variety of tissues, by promoting cellular proliferation and differentiation. FGF4 signals through the FGFR1c, 2c, 3c, and 4. Recombinant human FGF4 is a 19.7kD protein consisting of 182 amino acids.\n\nBiological Activity:\nThe ED50 as determined by the dose-dependent stimulation of thymidine uptake by BaF3 cells expressing FGF-receptors is (same/less than)0.5ng/ml, corresponding to a speci?c activity of \n(same/more than)2x10e6 units/mg. \n\nStorage and Stability:\nLyophilized powder may be stored at -20 degrees C. Stable for 12 months at -20 degrees C. Reconstitute with PBS, 0.1% HSA or BSA, aliquot and store at -20 degrees C. Reconstituted product is stable for 3 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.\n\n\nCountry of Origin: \nUSA
