Lyophilized recombinant human Keratinocyte Growth Factor (rhKGF) remains stable up to 6 months at -80 °C from date of receipt. Upon reconstitution, rhKGF should be stable up to 2 weeks at 4 °C or up to 3 months at -20 °C.
Keratinocyte Growth Factor (KGF) is a highly specific epithelial mitogen produced by fibroblasts and mesenchymal stem cells. KGF belongs to the heparin binding Fibroblast Growth Factor (FGF) family, and is known as FGF-7. However, in contrast to the FGF-1, which binds to all known FGF receptors with high affinity, KGF only binds to a splice variant of an FGF receptor, FGFR2-IIIb. FGFR2-IIIb is produced by most of the epithelial cells, indicating that KGF plays roles as a paracrine mediator. KGF induces the differen-tiation and proliferation of various epithelial cells, including keratinocytes in the epidermis, hair follicles and sebaceous glands, and is responsible for the wound repairs of various tissues, including lung, bladder, and kidney. Recombinant human Keratinocyte Growth Factor (rhKGF) produced in E. coli is a single non-glycosylated polypeptide chain containing 164 amino acids. A fully biologically active molecule, rhKGF has a molecular mass of 19.0 kDa analyzed by reducing SDS-PAGE. Synonyms: Keratinocyte Growth Factor, Fibroblast Growth Factor-7, HBGF-7, FGF-7
