Biological Activity for Tunicamycin

Tunicamycin is an antibiotic; inhibits GlcNAc phosphotransferase (GPT). Blocks the formation of N-glycosidic linkages by inhibiting the first step in glycoprotein synthesis. Activity induces ER stress and causes G1 arrest; can be used to induce autophagy. Tunicamycin contains four main components as follows:

  • Homolog A, n=8, C37H60N4O16, molecular weight = 816.90
  • Homolog B, n=9, C38H62N4O16, molecular weight = 830.93
  • Homolog C, n=10, C39H64N4O16, molecular weight = 844.95
  • Homolog D, n=11, C40H66N4O16, molecular weight = 858.99
The composition of this product will vary from batch to batch and can be found on the relevant certificate of analysis.

Worked at once.
By Bibha Dahal on 01/08/2020
Assay Type: In Vitro
Species: Human
Cell Line/Tissue: Human primary astrocytes

I dissolved tunicamycin in DMSO. I added tunicamycin at various concentrations (2uM, 4uM, 6uM, and 10uM) for 24 hours in human primary astrocytes and incubated at 37 C and 5% CO2. Next day, I collected lystates and ran a western blot. The first four lanes are tunicamycin added samples in increasing concentration and the last two lanes are without added. I looked for PERK activation using p-PERK antibody.

It took sometime to dissolve so you might want to warm once you add DMSO to tunicamycin in water bath.

Cell Line/Tissue: Human Intestine Subepithelial myofibroblasts

It is working well and easily dissolved into DMSO. I used 2.5, 5 µg/ml of Tunicamycin with serum free culture medium to treat the cells for 8h, 16h, 24h, and 48h.
