Merck, 407951-1MG, Ionomycin, Free Acid, Streptomyces conglobatus in Solution

General description
Highly specific for divalent cations (Ca²⁺ > Mg²⁺ >> Sr²⁺ = Ba²⁺). More effective than antibiotic A23187 as a mobile ion carrier for Ca²⁺. Complexes with Ca²⁺ between pH 7 and 9.5, causing significant absorption in the UV range; however, in contrast to A23187 (Cat. No. 100105), it is not fluorescent. Useful for studies of Ca²⁺ transport across biological membranes and measurement of cytoplasmic free Ca²⁺. Induces apoptotic neuronal degeneration in embryonic cortical neurons. Also induces cell cycle arrest in the G₁ interval of mature Burkitt lymphoma cell lines.
