Validation Data Gallery

• 

  Purity of recombinant human FGFbasic-TS 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 FGFbasic-TS (HZ-1285-GMP) stimulates dose-dependent proliferation of the HDFa human primary fibroblast cell line. Cell number was quantitatively assessed by Promega CellTiter 96® cell viability reagent. HDFa cells were treated with increasing concentrations of GMP recombinant FGFbasic-TS for 48 hours. The EC50 was determined using a 4-parameter non-linear regression model. Activity determination was conducted in triplicate on a validated bioassay. The EC50 range is 0.05-0.4 ng/mL.

  GMP-grade Recombinant human FGFbasic-TS (HZ-1285-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 basic-TS for 72hrs in defined medium. 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 0.4-2.5 ng/mL.

Background

Basic Fibroblast growth factor (FGFbasic), also known as bFGF, FGF2, FGF-β or HBGF-2, belongs to the FGF family. FGFbasic is involved in a number of biological processes including embryonic development and differentiation, neuron differentiation, survival, and regeneration, and the proliferation of cells of mesodermal origin and many cells of neuroectodermal, ectodermal, and endodermal origin (PMID 3272178, 3316527). FGFbasic is critical for human embryonic stem cells to remain in an undifferentiated state during cell culture (PMID 15782187).

Synonyms

Basic fibroblast growth factor, BFGF, FGF basic, FGF basic-TS, FGF2, FGFB, FGFbasic, FGFbasic-TS, HBGF 2
