Keratinocyte Growth Factor (KGF/ FGF7), human, active


SKU: 03-005 Research Area: Applications:


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. 1)



  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.


Activity: The ED50 as determined by a cell proliferation assay using MTS assay kit

(CellTiter 96, Promega) with human keratinocyte JCRB141 cells was < 10 ng/ml.

Purity: >95% as determined by SDS-PAGE (CBB staining)

Form: 1.0 mg / ml in PBS (10mM Na-phosphate, 150mM NaCl) pH7.2, 50% glycerol, filter-sterilized

Storage: -20°C or for long term storage -80°C
