Applicazioni

Nigericin sodium salt is a polyether ionophore which catalyzes the electroneutral exchange of alkali metal (K+) for H+ (antiport). It disrupts membrane potential and stimulates ATPase activity in mitochondria. It transports monovalent cations across membranes with the following specificity: K+ >Rb+ >Cs+ >>Na. It kills bacteria by facilitating the diffusion of ions across membranes. It is widely used in studies of the consequences of changes in membrane potential in variable systems.

Note

Stable under recommended storage conditions. Incompatible with oxidizing agents, acids, bases and heat.
