  • 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 Johannes Kepler Universitat)

Stability and Reconstitution

Stability and Storage Lyophilized proteins are stable for 1 year from the date of receipt if stored between (-20°C) and (-80°C). Upon reconstitution we recommend that the solution can be stored at (4°C) for short term or at (-20°C) to (-80°C) for long term. Repeated freeze thaw cycles should be avoided with reconstituted products.
Reconstitution Briefly centrifuge the vial before opening. It is recommended to reconstitute the protein in sterile water containing 0.1% endotoxin-free recombinant human serum albumin (HSA).

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).
