Overview

EGF stands for epidermal growth factor. Human EGF is a recombinant protein optimized for use in cell culture, differentiation studies, and functional assays.

Applications

Human EGF can be used for a variety of applications, including:

Proliferation and differentiation of a wide variety of cell types deriving from ectoderm and mesoderm.

Detailed product information

Background information

Epidermal growth factor (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. EGF stimulates the proliferation and differentiation of mesenchymal cells, acts as a mitogen for fibroblasts, epithelial and endothelial cells, and promotes colony formation of epidermal cells.

We measure the biological activity of each batch of MACS Premium-Grade Cytokines and state the results in the Certificate of Analysis (CoA). Based on the lot-specific activity, exact doses of active cytokine can be applied to cell culture experiments. This allows for reproducible cell culture conditions without the need for time-consuming lot-to-lot testing.

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 activities are stated in the Certificate of Analysis (www. miltenyibiotec.com/certificates).
