Product name
Tunicamycin, Protein glycosylation inhibitor -
Description
Antibiotic. Protein glycosylation inhibitor. -
Biological description
Nucleoside antibiotic that inhibits protein glycosylation. Inhibits GlcNAc phosphotransferase (GPT) and inhibits the transfer of N-acetylglucosamine-1-phosphate from UDP-N-acetylglucosamine to dolichol phosphate in the first step of glycoprotein synthesis. Inhibits N-linked glycosylation and blocks the formation of N-glycosidic protein-carbohydrate linkages. Active in vitro against Gram-positive bacteria, yeasts, fungi and viruses.

The cells were fixed with 4% PFA (10 min), permeabilized with 0.1% Triton-X for 5 mins and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1%PBS-Tween for 1h. The cells were then incubated overnight at +4°C with ab11419 at 5μg/ml and ab6046, Rabbit polyclonal to beta Tubulin - Loading Control, at 1/1000 dilution. Cells were then incubated with ab150117, Goat Anti-Mouse IgG H&L (Alexa Fluor® 488) at 1/1000 dilution (shown in green) and ab150084, Goat polyclonal Secondary Antibody to Rabbit IgG - H&L (Alexa Fluor® 594) at 1/1000 dilution (shown in pseudocolor red). Nuclear DNA was labeled with DAPI (shown in blue).
Image was taken with a confocal microscope (Leica-Microsystems, TCS SP8).
