Biological Activity

Na+/K+ ATPase modulator. Normalizes renal Na+/K+ ATPase pump function in mutant adducin- and endogenous ouabain-dependent forms of hypertension. Reduces blood pressure in Milan hypersensitive rats. Controls mania-like behaviors in Myshkin mice having a Na+/K+ ATPase α3 subunit mutation.

Preparing Stock Solutions

The following data is based on the product molecular weight 374.51. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.

Select a batch to recalculate based on the batch molecular weight:
Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
1 mM 2.67 mL 13.35 mL 26.7 mL
5 mM 0.53 mL 2.67 mL 5.34 mL
10 mM 0.27 mL 1.34 mL 2.67 mL
50 mM 0.05 mL 0.27 mL 0.53 mL
