CRC- β - Fc Chimera
Symansis" purified CRC-beta - Fchcx Chimera has N- and O-linked oligosaccharides, shown by a drop in observed MW on SDS-PAGE after treatment with PNGase F and a further drop after treatment with a glycosidase cocktail. Symansis" CRC-beta - Fchcx Chimera consists of 0-25% carbohydrate by weight. Densitometry of protein isoforms visualised by 2-DE. Spot trains are normal in human proteins and highlight the presence of multiple isoforms which differ according to their level of post-translational modification. The triangle indicates the theoretical MW and pI of the protein. 1D SDS-PAGE of Symansis" hcx protein before and after treatment with glycosidases to remove oligosaccharides. A drop in the observed MW after treatment indicates the presence of glycosylation. 1. Scott CL and Begley CG (1999) Int J Biochem Cell Biol 31:1011-1015 | |  |
