Abstract

Calmodulin levels in tissue or cellular extracts can be determined by competition with ¹²⁵I-calmodulin in a filtration-based direct binding assay. The method is rapid, uses readily available stable components, and possesses a selectivity and sensitivity comparable to that observed with immunoassay and phosphodiesterase activation. This assay provides a tool to readily probe changes in calmodulin levels in cells and tissues as a function of pathophysiologic state.
