Molecular Weight: 19 kDa

Accession number: P21781

Accession number: P21781

Purity: > 95 % (SDS-PAGE, RP-HPLC)

Form: lyophilized

Solubility: It is recommended to reconstitute the lyophilized KGF in bidest H2O not less than 100 μg/ml, which can then be further diluted to other aqueous solutions. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).

Activity: ED50: < 10 ng/ml, corresponding to a specific activity 105 IU/mg, stimulation of KGF-responsive BaF3 indicator cells (measured by 3H-thymidine uptake).

Description:
Keratinocyte growth factor (KGF) is a paracrine-acting, epithelial mitogen produced by cells of mesenchymal origin. Keratinocyte growth factor-1 (KGF-1) is the seventh member of the fibroblast growth factor family. It is produced by mesenchymal cells such as fibroblasts and upregulated in a variety of hyperplastic tissues. It is thought to play an important role in the paracrine growth control of normal epithelial cells. KGF stimulates the proliferation of primary and secondary human keratinocytes to the same extent as EGF. Recombinant human KGF-1 (FGF-7) produced in E. coli is a single, non-glycosylated, polypeptide chain containing 164 amino acids and having a molecular mass of 19 kDa. Recombinant KGF-1 is purified by proprietary chromatographic techniques.
