FGF-2, also referred to as basic FGF, is a growth factor primarily synthesized in fibroblasts, endothelial cells, and smooth muscle cells. The FGF family of myokines consist of 23 signalling proteins that interact with 4 different FGF receptors. These protein-protein signalling interactions contribute to the regulation of cellular proliferation, differentiation, tissue, development, angiogenesis, and wound healing.

Immobazyme's recombinant FGF-2 is produced in the methylotrophic yeast, Pichia pastoris and purified using immobilized metal ion affinity chromatography.
