Calmodulin-Sepharose Beads

Calmodulin is a highly conserved regulatory eukaryotic protein involved in various cellular processes such as glycogen metabolism, cytoskeletal control, neurotransmission, phosphate activity and control of NAD/NADP. The diverse functions of calmodulin rely on its ability to interact with, and regulate the activities of large number of its target proteins/enzymes. Calmodulin binds proteins usually through its hydrophobic sites, which are exposed due to conformational changes in the presence of Ca2+. However, some target proteins interact with Calmodulin in a calcium-independent manner. Calmodulin-Sepharose beads allow for specific enrichment of known or unknown calmodulin-binding proteins from biological samples. In addition, Calmodulin-Sepharose beads provide a convenient tool for affinity purification of calmodulin binding peptide (CBP) tagged recombinant proteins. Elution of CBP tagged proteins could be achieved by simply adding chelation ligand / removing Ca2+.
