Catalog Number: 5601
Chemical Name: 5,6-Dimethyl-9-oxo-9H-xanthene-4-acetic acid
Biological Activity
mSTING agonist; selective for mouse STING over human STING. Induces IFN-β and cytokine production from bone marrow-derived dendritic cells. Causes tumor regression following intratumoral administration in mouse tumor models. Induces an adaptive immune response to reduce systemic tumor growth and provides immunological memory against autologous tumor re-challenge. Also antiviral.

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?
