Protein Purification Protein Purification Resins
Calmodulin Sepharose™ 4B is calmodulin immobilised by the CNBr method to Sepharose™ 4B. Calmodulin is a highly conserved regulatory protein found in all eukaryotic cells. This protein is involved in many cellular processes such as glycogen metabolism, cytoskeletal control, neurotransmission, phosphate activity and control of NAD⁺/NADP⁺.

  • For single-step purification of native calmodulin-binding proteins
  • Suitable for tandem affinity purification (TAP) of protein complexes
  • Purification of calmodulin-regulated proteins from all eukaryotic cells
  • Cyanogen bromide activation coupling method
  • Stable to all commonly used aqueous solutions
  • Negligible volume variation due to changes in pH or ionic strength

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⁺ binding sites. The binding of enzymes may be enhanced if the enzyme substrate is present and enzymesubstratecalmoldulin-Ca²⁺ complexes are particularly stable.
