Calmodulin, Porcine Brain

Toxicity: Standard Handling (A)

Calmodulin (CaM) purified from porcine brain. A ubiquitous, calcium-binding protein that interacts with and regulates a wide variety of proteins, thus affecting different cellular functions and calcium-calmodulin-dependent signaling pathways. CaM mediates processes like inflammation, metabolism, apoptosis, muscle contraction, intracellular movement, short-term and long-term memory, nerve growth, and the immune response. Useful for applications requiring active pure calmodulin.

One unit is defined as the amount of calmodulin that will stimulate 0.01 unit of 3′5′-cyclic nucleotide phosphodiesterase to 50% of the maximum activity of the enzyme when saturated with CaM in the presence of 100 µM Ca²⁺ in a 3 ml reaction volume at 30°C, pH 7.5.

Lyophilized from 10 mM sodium phosphate buffer, 5% sucrose, pH 7.0.

Following reconstitution, aliquot and freeze (-20°C). Stock solutions are stable for up to 6 months at -20°C.
