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

The activity was determined by the dose-dependent stimulation of the proliferation of the Balb/3T3 cell line using the Promega CellTiter96® Aqueous Non-Radioactive Cell Proliferation Assay.

Recombinant human FGF-8b (HZ-1218) 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. The EC50 was determined using a 4- parameter non-linear regression model. The EC50 values range from 10-60 ng/mL.
 

Human induced pluripotent cells(iPSCs) were differentiated to dopaminergic neurons using HumanKine growth factors (GDNF-HZ-1311 and FGF8B- HZ-1103). The differentiation was confirmed by detection of expression of TAU(green), Alpha-Synuclein(red) and Thyrosine hydoxylase(TH)(yellow) in immunofluorescence.(Credits- Credits- Alessandro Bellapianta

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.
