Background: 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.

Concentration:

Activity: Measure by its ability to induce 3T3 cells proliferation. The ED₅₀ for this effect is <0.3 ng/mL. The specific activity of recombinant human FGF-1 is > 1 x 10⁶ IU/mg.

Sequence: Phe16-Asp155

Purity: > 98 % as determined by reducing SDS-PAGE.

Formulation: 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.

Reconstitution: Please refer to the printed manual for detailed information.

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

Calculated MW: 16.8 kDa

ObservedMW: 18 kDa
