  5. How can I store a solution of  5-(N-Ethyl-N-isopropyl)amiloride, Product A3085?

    We do not have solution stability information for  5-(N-Ethyl-N-isopropyl)amiloride.  The product is sensitive to light, particularly in solution. In general, drug solutions are best prepared immediately before use.  We recommend storing at -20°C in single use aliquots.

  6. What can I use to make a solution of 5-(N-Ethyl-N-isopropyl)amiloride, Product A3085?

    We test solubility of 5-(N-Ethyl-N-isopropyl)amiloride in methanol (10 mg/mL), yielding a clear yellow solution.  It is also soluble in DMSO, and in dilute aqueous acid.  It is insoluble in water.

  7. What concentration of Product A3085, 5-(N-Ethyl-N-isopropyl)amiloride, should I use in my experiment?

    We have the following references for the use of  5-(N-Ethyl-N-isopropyl)amiloride.  A review article mentions the use of EIPA at 1 micromolar to probe Na+ channels in rat alveolar epithelial cells; see: Matalon, S., et al., Biophysical and molecular properties of amiloride-inhibitable Na+ channels in alveolar epithelial cells. Am. J. Physiol., 271, L1-L22 (1996).  A study of the effects of EIPA on infarction in isolated rabbit hearts and cardiomyocytes has been reported; see: Sato, H., et al., The mechanism of protection from 5 (N-ethyl-N-isopropyl)amiloride differs from that of ischemic preconditioning in rabbit heart. Basic Res. Cardiol., 92, 339-350 (1997).
