Recombinant Human FGF basic Heat Stable GMP Protein Bioactivity.

The bioactivity of Recombinant Human FGF basic Heat Stable GMP Protein (Catalog # BT-FGFBHS-GMP) was measured in a cell proliferation assay using NR6R-3T3 mouse fibroblast cell line. The ED50 for this effect is 0.0500-0.600 ng/mL. Three independent lots were tested for bioactivity and plotted on the same graph to show lot-to-lot consistency of GMP FGF basic/FGF2 Heat Stabile protein.

Equivalent bioactivity of GMP and Animal-Free grades of recombinant human FGF basic heat-stable proteins.

Equivalent bioactivity of GMP (BT-FGFBHS-GMP) and Animal-Free (BT-FGFBHS-AFL) grades of Recombinant Human FGF basic Heat Stable proteins as measured in a cell proliferation assay using NR6R-3T3 mouse fibroblast cells (orange and green, respectively).

Higher iPSC fold expansion is observed with rhFGFb Heat Stable compared to wild type rhFGFb for daily and reduced feeding at 40 ng/mL

Human iPSCs were cultured for four passages in a commercial iPSC Expansion media containing 40 ng/mL of either rhFGFb Heat Stable (BT-FGFBHS) or wild type rhFGFb, Animal-Free (BT-FGFB-AFL). Media exchanges were performed following two feeding schedules. A). a daily feed schedule or B). a reduced feed schedule, where cells were double fed twice per week. Cells were plated at 5000 cells/cm2in a 6-well dish coated with Cultrex Ultimatrix (BME001). For each schedule, all conditions were passaged once either group reached ~60-70% confluency and counts were performed using a Cellaca™ High-Throughput Cell Counter. Count of each passage is shown comparing WT vs HS FGFb in both the A) daily feed or B) reduced feed schedule.

Background: FGF basic/FGF2/bFGF

FGF basic (also known as FGF-2 and HBGF-2) is an 18-34 kDa, heparin-binding member of the FGF superfamily of molecules. As a growth factor, FGF basic is expressed in a variety of cell types and involved in the regulation of cell proliferation, differentiation, migration and survival. FGF basic promotes self-renewal and upregulates pluripotency markers such as Oct4, Sox2 and Nanog, making it well-known for maintenance of pluripotency in embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs). These functions make FGF basic an important cell culture supplement in stem cell applications for regenerative medicine and clinical manufacturing protocols.

Our Heat Stable FGF basic has been engineered for thermostability and maintains its activity at 37℃ when compared to wild-type. Heat-stable FGF basic can enhance the flexibility and efficiency of cell culture by reducing the need for frequent media changes.
