Catalog Number: 3516
Chemical Name: Tunicamycin from Streptomyces sp.
Biological Activity
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.

Molarity Calculator
Calculate the mass, volume or concentration required for a solution

The molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol)
An example of a molarity calculation using the molarity calculator:
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
