GMP Recombinant Human EGF

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, unless otherwise stated in the respective Certificate of Origin. The product is lyophilized without carrier protein or preservatives.

Detailed product information

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.

Technical specifications

Identity/ Molecular mass: 6347 Da, determined by mass spectrometry. This corresponds to the mature form of human EGF including an N-terminal methionine (54 amino acids).
Purity: ≥ 95 % as determined by HPLC-SEC.
Endotoxin content: < 50 EU/mg, as determined by kinetic Limulus Amoebocyte Lysate (LAL) assay (Pharmacopoeia Europaea (Ph. Eur.)).
Residual host cell DNA content: < 20 ng/mg, as determined by quantitative PCR specific for E. coli genomic DNA.
Residual host cell protein content: < 10 µg/mg, as determined by E. coli HCP ELISA.
