Data Examples
Titration of CMP-C9-Biotin-Sialic Acid on Asialofetuin
|
Labeling and detection of N-glycans on fetal bovine fetuin. Asialofetuin (AF) was prepared from fetal bovine fetuin by treatment with Recombinant C. perfringens Neuraminidase, CF (Catalog # 5080-NM) and purified through size exclusion chromatography. Asialofetuin (8 µg) was incubated with indicated amounts of CMP-C9-Biotin-Sialic Acid (Catalog # ES201) with constant amount of Recombinant Human ST6GAL1 (aa 44-406) Protein (Catalog # 7620-GT) (0.1 µg) in 25 µl of 25 mM Tris, 10 mM MnCl2, pH7.5 buffer at 37oC for 30 minutes. The reactions were first separated on an SDS-PAGE and imaged by trichloroethylene (TCE) staining (upper panel). The separated proteins were then blotted to a nitrocellulose membrane and detected with conventional Streptavidin-HRP (Catalog # DY998) chemiluminescence reagents (lower panel). It is concluded that 0.1 nmol of CMP-C9-Biotin-Sialic Acid will achieve saturating labeling. |
