Densitometry scan demonstrating the purified human cell expressed protein exists in 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 ab83577 before and after treatment with glycosidases to remove oligosaccharides. Lane 1 – MW markers; Lane 2 – ab83577 ; Lane 3 – ab83577 treated with PNGase F to remove potential N-linked glycans; Lane 4 – ab83577 treated with a glycosidase cocktail to remove potential N- and O-linked glycans. 10 µg protein loaded per lane. Drop in MW after treatment with PNGase F indicates presence of N-linked glycans. Slight drop in MW after treatment with glycosidase cocktail suggests presence of O-linked glycans. Additional bands in lane 3 and lane 4 are glycosidase enzymes.
