| Bioactivity | BAPTA is a selective chelator for calcium. BAPTA, as calcium indicator, has high selectivity against magnesium and calcium. BAPTA is widely used as an intracellular buffer for investigating the effects of Ca2+ release from intracellular stores or influx via Ca2+-permeable channels in the plasma membrane. BAPTA can also inhibit phospholipase C activity independently of their role as Ca2+ chelators[1][2]. | ||||||||||||

| Invitro | BAPTA (0.3-30 μM; 1 h) can be used for the prevention of [Ca2+]-induced cell damage, but disturbe calcium signalling in isingle differentiated NH15-CA2 neuroblastoma and glioma hybrid cells[3].BAPTA (0-10 mM) inhibits phospholipase C (PLC) activity in a dose-dependent manner, and is unrelated to Ca2+[2]. | ||||||||||||
