Validation Data Gallery

• 

  Purity of recombinant human FGF-4 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 GMP FGF-4 (HZ-1218-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 with 0.02% FBS during treatment with increasing concentrations of recombinant human FGF-4 for 72hrs in defined medium. The EC50 was determined using a 4- parameter non-linear regression model. Activity determination was conducted in triplicate on a validated assay. The EC50 values range from 6-30 ng/mL.

Background

Fibroblast growth factor-4 (FGF-4) plays an important physiologically role in the self-renewal of human embryonic stem cells (PMID 21990129). It also promotes stem cell proliferation and may aid in differentiation. Xeno-free Recombinant Human FGF-4 is expressed in human 293 cells as a monomeric glycoprotein with an apparent molecular mass of 17 and 27 kDa.
