Sodium ionophore VI is a sodium-selective ionophore that can be used in ion-selective electrodes to monitor sodium levels in aqueous solutions.1 It is selective for sodium over calcium, magnesium, lithium, ammonium, and potassium ions. Sodium ionophore VI has been used in electrodes to determine the levels of sodium ions in human urine and serum, as well as in X. laevis oocytes.2,3
