Catalog Number: 4312
Chemical Name: (2R)-2-[(2R,3S,6R)-6-[[(2S,4R,5R,7R,9R,10R)- 2-[(2R,5S)-5-[(2R,3S,5R)-5-[(2S,3S,5R,6R)-6-Hydroxy- 6-(hydroxymethyl)-3,5-dimethyl-2-tetrahydropyranyl]-3-methyl- 2-tetrahydrofuranyl]-5-methyl-2-tetrahydrofuranyl]-9-methoxy- 2,4,10-trimethyl-1,6-dioxaspiro[4
Biological Activity
Potassium ionophore, exchanges K+ for H+ across biological membranes, in a similar manner to Valinomycin (Cat. No. 3373). Stimulates mitochondral ATPase activity and disrupts membrane potential. Also acts as an ionophore for Pb2+ with no activity with other divalent cations. Antibiotic derived from Streptomyces hygroscopius.

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?
