Description

General description

A ubiquitous Ca2+-binding protein distributed in eukaryotic cells that serves as a major physiological effector for a wide range of cellular responses. The Ca2+-calmodulin complex is involved in the maintenance of intracellular Ca2+ homeostasis, as well as in the regulation of the intracellular concentration of other second messengers, such as cyclic AMP and inositol trisphosphate. Calmodulin highly purified from bovine brain.



Note: This product is not to be used for animal treatment, in vivo research or in any other contact procedure with livestock.

Unit Definition

One unit is defined as the amount of calmodulin that gives rise to 50% of the maximal enzyme activation of a standard level of activator-deficient calcineurin.

Physical form

Lyophilized from 30 mM HEPES, 1 mM CaCl₂, 0.1 mM DTT, pH 7.4.

Reconstitution

Following reconstitution, aliquot and freeze (-20°C or -70°C). Aqueous stock solutions are stable for up to 2 months at -20°C or for up to 4 months at -70°C.
