FGF-basic is one of 23 known members 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. FGF-basic is a non-glycosylated heparin binding growth factor that is expressed in the brain, pituitary, kidney, retina, bone, testis, adrenal gland liver, monocytes, epithelial cells and endothelial cells. FGF-basic signals through FGFR 1b, 1c, 2c, 3c and 4. Recombinant murine FGF-basic is a 16.2kD protein consisting of 145aa. Source: Recombinant protein corresponding to mouse FGF-basic, expressed in E.coli. Biological Activity: Assay #1: Determined by the dose-dependent stimulation of thymidine uptake by BaF3 cells expressing FGF receptors. The ED50 was found to be 0.1ng/ml corresponding to a specific activity of 1x10e7 units/mg. Assay #2: Determined by a cell proliferation assay using balb/c 3T3 cells. The ED50 was found to be 1.0ng/ml, corresponding to a specific activity of 1x10e6 units/mg. Endotoxin: <0.1ng/ug (1EU/ug) AA Sequence: MPALPEDGGA AFPPGHFKDP KRLYCKNGGF FLRIHPDGRV DGVREKSDPH VKLQLQAEER GVVSIKGVCA NRYLAMKEDG RLLASKCVTE ECFFFERLES NNYNTYRSRK YSSWYVALKR TGQYKLGSKT GPGQKAILFL PMSAKS Storage and Stability: May be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
