Keratinocyte Growth Factor (KGF), also known as Fibroblast Growth Factor 7 (FGF-7), is a member of fibroblast growth factor (FGF) family. Although FGF-7 has heparin binding activity similar to FGF-1, its mitogenic activity is predominantly exhibited in keratinocytes. It is not effective to fibroblasts and endothelial cells.
The human FGF-7 lacking the signal sequence (1-31 aa) was expressed in E. coli and purified by the chromatographic procedures. This product is an intact enzyme without tag with 19 kDa size (Fig.)

Applications
1. Mitogen for epithelial cells             
2. Western blot control for anti-FGF-7 antibodies
3. Acceleration of wound healing is implied.
4. Acceleration of hair development is implied.
