Catalog Number: 4536
Alternate Names: R 848
Chemical Name: 1-[4-Amino-2-(ethoxymethyl)-1H-imidazo[4,5-c]quinolin-1-yl]-2-methylpropan-2-ol
Biological Activity
Toll-like receptor 7 (TLR7) agonist. Induces upregulation of IL-6, IL-12, IFN-γ and iNOS expression in mouse bone marrow-derived macrophages (BMMs). Inhibits RANKL-induced osteoclast differentiation in mouse BMMs and human peripheral blood monocytes. Also promotes the differentiation of MDSCs into macrophages and dendritic cells. Proinflammatory and 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?
