Overview

Epidermal growth factor (EGF) is a small mitogenic polypeptide that stimulates the proliferation and differentiation of a wide variety of cells of ectodermal and mesodermal origin, including fibroblasts, epithelial cells, and endothelial cells. MACS GMP Recombinant Human EGF is designed for ex vivo cell culture processing. No animal- or human-derived materials were used for the manufacture of this product. The product is lyophilized without carrier protein or preservatives.

Background information

EGF is the prototype of the large family of EGF-like proteins with a common structural motif comprising three intramolecular disulfide bonds. EGF is produced by various cell types like mammary gland cells, gut epithelial cells, and cells in the nervous system and the kidney. Production of EGF is induced by testosterone and inhibited by estrogens. In vitro, EGF stimulates the proliferation and differentiation of mesenchymal cells, acts as a mitogen for fibroblasts, neural precursors, epithelial and endothelial cells, and promotes colony formation of epidermal cells.

Applications

MACS GMP Recombinant Human EGF can be used as an ingredient for many cell culture applications. EGF can support the maintenance of ectodermal and mesodermal progenitor cells, and stimulates the proliferation and differentiation of a wide variety of cell types deriving both from ectoderm and mesoderm.

Biological activity

The specific activity is determined by proliferation assay according to Robinson and Gaines-Das¹ using 3T3 cells. The proliferation assay was calibrated with the international standard for human EGF (NIBSC code 91/530) provided by the National Institute for Biological Standards and Control.Specific activity: ≥ 5×10⁵ IU/mg
