WebNigericin sodium salt is a 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 Pb 2+ with no activity with other divalent cations.
