Validation Data Gallery

• 

  Purity of recombinant human FGF-8b 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.

• 

  GMP Recombinant human FGF-8b (HZ-1103-GMP) stimulates dose-dependent proliferation of the NIH/3T3 mouse fibroblast cell line. Viable cell number was quantitatively assessed by Prestoblue Cell Viability Reagent. NIH/3T3 cells were serum starved in 0.02% FBS with 1 ug/mL heparin during treatment with increasing concentrations of recombinant human FGF-8b for 72hrs. Activity determination was conducted in triplicate on a validated bioassay. The EC50 was determined using a 4- parameter non-linear regression model. The EC50 values range from 10-60 ng/mL.

Background

Fibroblast growth factor 8 (FGF8), also known as AIGF and HBGF-8, 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). FGF8 stimulates growth in an autocrine manner in normal individuals but mediates hormonal action during tumorigenesis (PMID 17512240). Defects in FGF8 cause Kallmann syndrome type 6 (KAL6) and idiopathic hypogonadotropic hypogonadism (IHH) (PMID 18596921).
