Description

Fibroblast Growth Factor basic Protein, Human recombinant

Overview

Fibroblast Growth Factor-basic (FGF-b) is a heparin binding growth factor which stimulates the proliferation of a wide variety of cells including mesenchymal, neuroectodermal and endothelial cells. FGF-b also exerts a potent angiogenic activity in vivo. Human FGF-b is a 17.2 kDa protein containing 154 amino acid residues.

Background Information

Fibroblast Growth Factor-basic (bFGF) is a heparin binding growth factor which stimulates the proliferation of a wide variety of cells including mesenchymal, neuroectodermal and endothelial cells. bFGF also exerts a potent angiogenic activity in vivo. Human bFGF is a 17.2 kDa protein containing 154 amino acid residues. Xu, et al. demonstrated that bFGF synergizes with the BMP antagonist noggin to sustain undifferentiated proliferation of human embryonic stem (hES) cells under feeder-free conditions. GF003-AF was developed without animal-based ingredients and can be used for the culture of hES cells in a feeder-free, animal-free culture system.

 

Product Information

Presentation

Lyophilized from a 0.7 mg/mL solution in 5mM Tris, pH 7.6 with 150 mM NaCl.

 

Applications

Application

The Fibroblast Growth Factor-basic (FGF-b) is a heparin binding growth factor which stimulates the proliferation of a wide variety of cells including mesenchymal, neuroectodermal & endothelial cells.

Key Applications

  • Stem Cell Culture
  • Cell Culture

Application Notes

For most in vitro applications, bFGF exerts its biological activity in the concentration range of 0.1 to 10.0 ng/mL. Responding cells are (partial list): Endothelial, mesenchymal cells. Human ES cells require concentrations in the range of 4 to 100 ng/mL, depending on the method of culture.

Optimal working dilutions must be determined by end user.

Specific Activity

Chemicon's Human FGF-b is fully biologically active when compared to standards. The ED50 was determined by the dose-dependent stimulation of thymidine uptake by NIH3T3 cells expressing FGF receptors.

Entrez Gene Number

Entrez Gene Summary

The protein encoded by this gene is a member of the fibroblast growth factor (FGF) family. FGF family members bind heparin and possess broad mitogenic and angiogenic activities. This protein has been implicated in diverse biological processes, such as limb and nervous system development, wound healing, and tumor growth. The mRNA for this gene contains multiple polyadenylation sites, and is alternatively translated from non-AUG (CUG) and AUG initiation codons, resulting in five different isoforms with distinct properties. The CUG-initiated isoforms are localized in the nucleus and are responsible for the intracrine effect, whereas, the AUG-initiated form is mostly cytosolic and is responsible for the paracrine and autocrine effects of this FGF.

UniProt Number

UniProt Summary

FUNCTION: SwissProt: P09038 # The heparin-binding growth factors are angiogenic agents in vivo and are potent mitogens for a variety of cell types in vitro. There are differences in the tissue distribution and concentration of these 2 growth factors.
SIZE: 155 amino acids; 17254 Da
SUBUNIT: Monomer. Interacts with CSPG4 and FGFBP1. Found in a complex with FGFBP1, FGF1 and FGF2.
SIMILARITY: SwissProt: P09038 ## Belongs to the heparin-binding growth factors family.
MISCELLANEOUS: This protein binds heparin more strongly than does aFGF.

Storage and Shipping Information

Storage Conditions

Maintain the lyophilized material at -20°C until expiration date as stated on the label.

General applications:
After a quick spin, reconstitute in 0.1M phosphate buffer, pH 6.8, to a concentration of 0.1-1.0 mg/mL. Reconstituted bFGF should be stored in working aliquots at -20 °C for up to six months. Multiple freeze/thaw cycles will result in significant loss of activity.

For Human ES cell culture:
After a quick spin, reconstitute to 10 μg/mL in a filtered solution of 0.5% BSA, 1 mM DTT, and 10% glycerol in Dulbecco's PBS. Aliquot and store at -20°C for up to six months. This solution can then thawed and diluted to 4 ng/mL for the culture of human ES cells with a feeder layer, or to 8 ng/mL to supplement mouse embryonic fibroblast-conditioned medium (for feeder-free human ES cell culture).
