General description
FGF-acidic 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. FGFacidic 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 human FGFacidic is a 16.0 kDa protein consisting of 141 amino acid residues.
Product Source: Protein is expressed in E.coli.
The protein is manufactured without the use of any animal products/reagents and is considered Animal-Free and can be used in protocols where possible transmisson of animal viruses and contamination must be avoided.

Bioactivity assay:
Assay #1: The ED50 as determined by the dose-dependent stimulation of thymidine uptake by BaF3 cells expressing FGF receptors is ≤ 10 ng/ml corresponding to a specific activity of ≥ 1 x 10^5 units/mg.
Assay #2: The ED50 was determined by a cell proliferation
assay using balb/c 3T3 cells is ≤ 0.5 ng/ml in the presence
of 10 μg/ml heparin, corresponding to a specific activity of
≥ 2 x 10^6 units/mg.
