Fibroblast growth factor 2 (FGF-2), also termed basic FGF, belongs to the family of heparin-binding growth factors. FGF-2 functions as a wide-spectrum mitogenic, angiogenic, and neurotrophic factor and stimulates the proliferation of a wide variety of cells including mesenchymal, neuroectodermal, and endothelial cells.
MACS GMP Recombinant Human FGF-2 is designed for
ex vivo
cell culture processing. No animal- or human-derived materials were used for the manufacture of this product, unless otherwise stated in the respective Certificate of Origin. The product is lyophilized without carrier protein or preservatives.
Disclaimer
MACS GMP Products are for research use and
ex vivo
cell culture processing only, and are not intended for human
in vivo
applications. For regulatory status in the USA, please contact your local representative.
Applications
MACS GMP Recombinant Human FGF-2 can be used for a variety of applications, including the culture of undifferentiated human embryonic stem cells
2,3
or the expansion of mesenchymal stromal cells
4,5
.
Quality statement
MACS GMP Products are manufactured and tested under a quality management system (ISO 13485) and are in compliance with relevant GMP guidelines. They are designed following the recommendations of USP <1043> on ancillary materials.
Biological activity
The specific activity is determined by proliferation assay according to Robinson and Gaines-Das
1
using 3T3 cells. The proliferation assay was calibrated with the international standard for human FGF-2 (NIBSC code 90/712) provided by the National Institute for Biological Standards and Control.
Mass spectrometry analysis (ESI-MS) of MACS GMP Recombinant Human FGF-2. The peaks correspond to the mature form of human FGF-2, both with the N-terminal proline (146 amino acids) and without the N-terminal proline (145 amino acids), respectively.
