Analysis Note

The proliferative activity is tested in culture using the murine hematopoietic cell line BaF3.

Biochem/physiol Actions

Keratinocyte growth factor (KGF, 18.9 kDa, 163 amino acids) includes a secretory signal sequence and shares 39% identity with FGF-Basic. It is expressed in a number of stromal fibroblast cell lines but absent from normal glial cells and epithelial cell lines. KGF stimulates proliferation and differentiation of keratinocytes and other cells in the epithelium and induces chemotaxis of microvascular endothelial cells and neovascularization of rat cornea.

Physical form

Lyophilized from a 0.2 μm filtered solution in phosphate buffered saline containing 0.5 mg bovine serum albumin.
