Calmodulin Protein, Human

Cat. No.: HY-P7710
Handling Instructions

Calmodulin Protein, Human is a recombinant human Calmodulin expressed in E. coli. Calmodulin is a low molecular weight, acidic, calcium binding protein which mediates the Ca2+ regulation of a wide range of physiological processes throughout eukaryotic organisms[1].

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O or PBS.

Storage & Stability

Stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage.


Room temperature in continental US; may vary elsewhere.


At low free Ca2+ concentrations, such as exist in resting muscle sarcoplasm, calmodulin exists in the Ca2+-free form in which state it does not generally interact with a target protein. Following an appropriate stimulus, the free Ca2+ concentration rises whereupon Ca2+ binds to calmodulin which undergoes a conformational change enabling it to interact with a target protein(s)[1].

  • Reconstitution Calculator

  • Dilution Calculator

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×
