Catalog Number: 4286
Chemical Name: 4-[5-(4-Methoxyphenyl)-2-oxazolyl]-9H-fluoren-9-one
Biological Activity
Inhibitor of microtubule polymerization in vitro. Interacts with tubulin dimers and promotes the accumulation of mammalian cells in apoptosis. Potentiates antiproliferative effects of vinblastine (Cat. No. 1256) in H2B-GFP HeLa cells. Originally thought to inhibit CENP-E ATPase activity.

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?
