Description
Ivermectin B1a is the main component (>80%) of the anthelmintic, ivermectin. It produces antiparasitic activity by binding to glutamate-gated chloride channels expressed on nematode neurons and pharyngeal muscle cells, inducing irreversible channel opening and very long-lasting hyperpolarization/depolarization of the neuron/muscle cell, thereby blocking further function (EC50 = 104 nM).Related product price
