FGF acidic

FGF-acidic is one of 23 known members of the FGF family. Proteins of this family play a central role during prenatal development, postnatal growth and regeneration of a variety of tissues, by promoting cellular proliferation and differentiation. FGF-acidic is a non-glycosylated heparin binding growth factor that is expressed in the brain, kidney, retina, smooth muscle cells, bone matrix, osteoblasts, astrocytes and endothelial cells. FGF-acidic has the ability to signal through all the FGF receptors. Recombinant rat FGF-acidic is a 15.9 kDa protein consisting of 141 amino acid residues.

Assay Protocol

Reconstitute in 5 mM Sodium Phosphate, pH 7.2 to a concentration of ≤ 0.5 mg/mL. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.

Endotoxin

< 0.1 ng/µg of protein (< 1EU/µg)

Purity

> 98% by SDS-PAGE & HPLC analyses

Bioactivity

Determined by a cell proliferation assay using balb/c 3T3 cells. The expected ED50 is ≤ 0.1 ng/ml, in the presence of 10 µg/ml heparin, corresponding to a specific activity of ≥ 1 x 107 units/mg.
