Calmodulin (Agarose) 4B

Applications:

Calmodulin-Separopore® 4B is used for affinity purification of calmodulin-binding proteins including calmodulin-regulated proteins in eukaryotic cells and recombinant proteins containing calmodulin-binding peptide fusion tag. Calmodulin binds proteins principally through their interactions with hydrophobic sites on its surface. These sites are exposed after a conformational change induced by the action of Ca²⁺ on separate Ca²⁺-. The binding of enzymes may be enhanced if the enzyme substrate is present and enzyme substrate calmoldulin-Ca²⁺ complexes are particularly stable.
