製品名Tunicamycin, Protein glycosylation inhibitor
製品の詳細Antibiotic. Protein glycosylation inhibitor.
生理活性の詳細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)
保存方法Store at +4°C. Store under desiccating conditions. The product can be stored for up to 12 months.
溶解性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.
