General description

Calmodulin purifed from human brain.
Calmodulin purifed from human brain. Calmodulin is 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.

Warning

Toxicity: Standard Handling (A)

Unit Definition

One unit is defined as the amount of calmodulin that will give rise to 50% of the maximal enzyme activation of a standard level of activator-deficient 3ʹ,5ʹ-cyclic nucleotide phosphodiesterase.

Physical form

Lyophilized from protein solution with 2 mM EDTA.

Reconstitution

Reconstitute with distilled water. H₂O (1 mg/ml)
