Recombinant Human FGF-1/FGFa Protein

C-His

Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80°C. Reconstituted protein solution can be stored at 4-8°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.

FGF acidic; also known as ECGF; FGF-1and HBGF-1; 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. It is a mitogenic peptide that is produced by multiple cell types and stimulates the proliferation of cells of mesodermal; ectodermal; and endodermal origin. Its association with heparan sulfate is a prerequisite for activation of FGF receptors. Internalized FGF acidic migrates to the nucleus where it is phosphorylated by nuclear PKC delta; exported to the cytosol; dephosphorylated; and degraded. Intracellular FGF acidic inhibits p53 activity and proapoptotic signaling.

< 0.1 EU per μg of the protein as determined by the LAL method.

Lyophilized from sterile PBS, pH 8.0.
Normally 5% - 8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.
