Light yellow film. PROTECT FROM LIGHT. PACKAGED UNDER INERT GAS. Highly specific for divalent cations and more effective than A23187 (Cat. No. 100105) as a mobile ion carrier for Ca²⁺. Complexes with Ca²⁺ between pH 7 and 9.5. In contrast to A23187, 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 and cell cycle arrest in the G₁ phase in mature Burkitt lymphoma cell lines. Purity: ≥90% by HPLC. Absorption max. (280 nm, MeOH): 18,600 M^-1cm^-1. RTECS NO0600000, CAS 56092-81-0.
