Calcium Ionophore II is widely used in biological and biochemical research to study calcium signaling pathways within cells. It facilitates the transport of calcium ions across cell membranes, allowing researchers to manipulate intracellular calcium levels. This is particularly useful in investigating the role of calcium in cellular processes such as muscle contraction, neurotransmitter release, and cell proliferation. Additionally, it is employed in fertilization studies to artificially activate oocytes by increasing intracellular calcium concentrations. Its application extends to the study of calcium-dependent enzymes and the regulation of cellular functions in response to calcium fluctuations.
