Specifications for Human FGF-2

Overview

Recombinant human FGF-2 (FGF-basic or bFGF) is used for the cultivation of undifferentiated embryonic and induced pluripotent stem cells. The basic fibroblast growth factor (FGF) also promotes the growth of a variety of cell types belonging to the mesodermal, ectodermal, and endodermal lineage. Thus, it has implications for diverse processes, such as angiogenesis, tissue repair, neuronal functions or embryogenesis.

Applications

Human FGF-2 can be used for a variety of applications, including:
  • Stimulation of proliferation and differentiation of several cell types, such as mesenchymal stromal cells, neural cells, and endothelial cells.
  • Long-term maintenance and propagation of undifferentiated embryonic and induced pluripotent stem cells.
  • Differentiation of neural cells starting from embryonic and induced pluripotent stem cell cultures.

Detailed product information

Background information

Fibroblast growth factor 2 (FGF-2), also termed fibroblast growth factor basic (FGF-b) or basic FGF (bFGF), belongs to the FGF family. It 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. FGF-2 has been implicated in a multitude of physiological and pathological processes, including limb development, angiogenesis, wound healing, and tumor growth.

Quality description

Research-grade
cytokines are suitable for a wide variety of cell culture applications. They are sterile-filtered prior to lyophilization. Generally, endotoxin levels are <0.1 ng/μg (<1 EU/μg), and purities are >95%. The biological activity is tested in appropriate bioassays.
Premium-grade
cytokines offer the convenience of high and well-defined biological activities and allow exact unit dosing for demanding applications. The biological activity is determined after lyophilization and reconstitution, and normalized to WHO/NIBSC standards whenever available. In general, endotoxin levels are <0.01 ng/μg (<0.1 EU/μg), and purities are >97%. Lot-specific certificates of analysis are available on request (macstec@miltenyibiotec.de).
