Validation Data Gallery

• 

  Purity of recombinant human FGF-7 was determined by SDS- polyacrylamide gel electrophoresis. The protein was resolved in an SDS- polyacrylamide gel in reducing and non-reducing conditions and stained using Coomassie blue.

• 

  Recombinant human FGF-7 (HZ-1100) Stimulates dose-dependent proliferation of the 4MBr-5 Monkey epithelial cell line. Viable cell number was quantitatively assessed by PrestoBlue Cell Viability Reagent. 4MBr-5 ells were treated with increasing concentrations of recombinant human FGF-7 for 120 hours. The EC50 was determined using a 4- parameter non-linear regression model. The EC50 values range from 4-20 ng/mL.

Background

Fibroblast growth factor 7 (FGF-7), also known as keratinocyte growth factor (KGF), belongs to the FGF family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion (PMID 11276432, 15863033). FGF-7 is a potent epithelial cell-specific growth factor, whose mitogenic activity is predominantly exhibited in keratinocytes (PMID 15327889).
