Specifications

KGF is a potent specific mitogen for many epithelial cells but not for fibroblasts and endothelial cells. KGF 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.
Catalog #K0201-01A
Recombinant human KGF is a single, non-glycosylated, polypeptide chain containing 164aa and having a molecular weight of 19kD. The sequence of the first five N-terminal aa was determined to be Met-Cys-Asn-Asp-Met. Contains less than 1% dimers and aggregates. ActivityThe ED50 as determined by the dose-dependent stimulation of KGF-responsive BaF3 indicator cells (measured by 3H-thymidine uptake) is <10ng/ml, corresponding to a specific activity of 10Units/mg.
Storage and StabilityLyophilized powder may be stored at -20°C. Stable for 12 months after receipt at -20°C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing.
