CellGenix® rh FGF-2

GMP and Preclinical grade

CellGenix Recombinant Human FGF-2, also known as bFGF, reliable improves proliferation of mesenchymal stem cells (MSCs). It in addition supports proliferation and differentiation of chondrocytes and supports propagation of undifferentiated pluripotent stem cells (PSCs). CellGenix rh FGF-2 is produced in our dedicated animal-free facility ensuring maximum safety for optimal use in ATMP manufacturing.

General Information

Fibroblast Growth Factor-2 (FGF-2) is a basic fibroblast growth factor. It amongst others plays an important role in wound healing and tumor development by mediating the formation of new blood vessels.

FGF-2 is used in the cell and gene therapy space for the expansion of bone marrow and adipose tissue derived MSCs.

GMP Grade

CellGenix GMP Recombinant Human FGF-2 is produced following all applicable GMP guidelines and allows for the safe use in accordance with USP Chapter <1043>, Ph. Eur. General Chapter 5.2.12 and ISO Technical Standard 20399.

Our GMP cytokines are provided with documented evidence of purity, potency, consistency and stability. In combination with our expert regulatory and technical support this will help simplify your raw material qualification and validation efforts.

Technical Details

Expressed in E. coli

Human FGF-2, accession # P090938, Ala135-Ser288


Lyophilized from a 0.2 µm-filtered solution containing 25 mM sodium phosphate, 400 mM sodium chloride, 10 mM glutathione (red.) and 5% mannitol, pH 6.5

Both product grades are produced under the same conditions in a GMP facility, ensuring an equal product quality and performance. We offer a more comprehensive QC testing including tighter specifications and documentation for our GMP products: Preclinical vs GMP.
