Human EGF R - FcA Chimera (GWB-1C8287)



25 ug


Source: A DNA sequence encoding the signal peptide and extracellular domain of human EGF R (aa 1-525) was fused to the Fc region of human IgG1 (aa 90-330). The chimeric protein was expressed in modified human 293 cells.

Molecular Mass: Under reducing conditions EGF R - FcB Chimera migrates as a broad band between 85 and 110 kDa on SDS-PAGE due to post-translation modifications, in particular glycosylation. This compares with unmodified EGF R - FcB Chimera that has a predicted monomeric molecular mass of 83 kDa.

PI: EGF R - FcB Chimera separates into a number of glycoforms with a pI between 6.0 and 8.5 on 2D PAGE due to post-translational modifications, in particular glycosylation. This compares with the unmodified EGF R - Fc Chimera that has a predicted pI of 7.8.

% Carbohydrate: purified EGF R - FcB Chimera consists of 5-30% carbohydrate by weight.

Glycosylation: EGF R - FcB Chimera contains N- and O-linked oligosaccharides.

Reconstitution: It is recommended that 0.5 ml of sterile phosphate-buffered saline be added to the vial. EGF R, also known as Epidermal growth factor receptor, is a member of the ErbB family receptors. EGF R is present in most, if not all, normal human epithelial cells. EGF R main function is as a receptor for EGF, but it also acts as a receptor for other members of the EGF family such as TGF-alpha, amphiregulin, and heparin-binding EGF-like growth factor. When EGF attaches to human EGF R it activates the enzyme tyrosine kinase, triggering reactions that cause the cells to grow and multiply. EGF R is a 479 amino acid glycoprotein that consists of an extracellular receptor domain, a transmembrane region, and an intracellular domain with tyrosine kinase function.
