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.
This compound is a mixture of the homologs of tunicamycin: A, B, C and D which vary in the carbon chain length (n=8 to 11)
分子式C39H64N4O16 (for tunicamycin C, n = 10)
存放说明Store at +4°C. Store under desiccating conditions. The product can be stored for up to 12 months.
溶解度概述Soluble in DMSO to 50 mM
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
Toxic, refer to SDS for further information.

ab11419 staining DDIT3 in HeLa (Human epithelial cell line from cervix adenocarcinoma) cells +/- Tunicamycin 1.5μM, 6 hours (ab120296).
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).
