The A23187-induced cytotoxicity cytometrically examined in rat thymocytes.
By Lutpine Rachel on 01/02/2020
Assay Type: In Vitro
Species: Human

A23187 is used to induce Ca(2+)-dependent cell death by increasing intracellular Ca(2+) concentration ([Ca(2+)](i)) under in vitro condition. Since this ionophore also increases membrane permeability of metal divalent cations such as Zn(2+) and Fe(2+) rather than Ca(2+), trace metal cations in cell suspension may affect Ca(2+)-dependent cell death induced by A23187. Therefore, the effects of chelators for divalent metal cations, EDTA and TPEN, on the A23187-induced cytotoxicity were cytometrically examined in rat thymocytes.

The cytotoxicity of A23187 was attenuated by 1mM EDTA while it was augmented by 50 microM EDTA and 10 microM TPEN.
