Background: Fibroblast growth factor 2(FGF2) is a secreted protein and belongs to the heparin-binding growth factors family. FGF2 is produced by epithelial; tumor and other cell types. It involved in developmental processes and regulates differentiation; proliferation; and migration; FGF2 is a critical factor for growing embryonic stem cells in culture without inducing differentiation. FGF2 has a high affinity for heparan sulfate and binding is a step in the FGF basic activation of FGFR tyrosine kinase.
Activity: Measure by its ability to induce proliferation in 3T3 cells. The ED50 for this effect is < 2 ng/mL.
Purity: > 98 % as determined by reducing SDS-PAGE.
Formulation: Lyophilized from a solution containing 0.01% sarkosyl in 1X PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the printed manual.
Endotoxin: Please contact us for more information.
