Catalog Number: 1793
Biological Activity
Potent and selective antagonist for the human type I interleukin-1 (IL-1) receptor (IC50 values are 8 nM, > 6.7 mM and > 200 mM for human type I, human type II and murine type I IL-1 receptors respectively). Blocks IL-1-induced expression of ICAM-1 and E-selectin in HUVECs and IL-1β induction of IL-8 in human dermal fibroblasts. Reduces IL-1β-induced IL-6 production and exhibits anti-inflammatory activity in vivo.

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?
