Valinomycin Inhibitor

Valinomycin is a dodecadepsipeptide antibiotic, which is obtained from several Streptomyces strains. Valinomycin functions as a potassium-specific transporter and promotes the movement of K+ through lipid membranes. Excessive K+ efflux is an ionic mechanism underlying apoptosis.

Small volumes of Valinomycin, inhibitor vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
