Ionomycin calcium salt

(HB1001)

Product overview

  • Name
    Ionomycin calcium salt
  • Short description
    Calcium ionophore. Stimulates cytokine production.
  • Biological description

    Potent calcium ionophore which shows selectivity for Ca2+ over Mg2+ and K+. Acts as a Ca2+ carrier. Calcium salt of ionomycin.

    Directly stimulates store-regulated cation entry across biological membranes to enhance Ca2+ influx and increase intracellular Ca2+ concentration.

    Synergies with with phorbol myristate acetate (PMA) to enhance activation of PKC. Frequently used in combination with PMA to stimulate T-cell activation and intracellular production of cytokines.

    Also induces apoptosis.

    Calcium ionophore A23187 also available.
