Calcium Assay Kit

Cayman's Calcium Assay provides a quick, reliable method for determining total calcium concentration in a variety of biological samples, as well as tissue homogenates and cell lysates. The assay utilizes an optimized variant of the well-established o-Cresolphthalein-calcium reaction in which a vivid purple complex that absorbs between 560 and 590 nm is formed in the presence of calcium.
