Catalog Number: 4943
Chemical Name: N-[2-[(Acetyloxy)methoxy]-2-oxoethyl]-N-[(3',6'-diazido-3-oxospiro[isobenzofuran-1(3H),9'-[9H]xanthen]-5-yl)carbonyl]glycine (acetyloxy)methyl ester
Biological Activity
Reported to be a hydrogen sulphide (H2S) fluorescent probe. Contains an acetoxymethyl ester, which enhances cell permeability and is hydrolyzed inside the cell to trap the probe. Used to visualize VEGF-induced H2S production in human umbilical vein endothelial cells (HUVECS). Excitation wavelength ~ 495 nm; emission maximum ~ 520 nm.

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?
