| Bioactivity | BAPTA tetrasodium is a selective chelator for calcium. BAPTA tetrasodium, as calcium indicator, has high selectivity against magnesium and calcium. BAPTA tetrasodium 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 tetrasodium can also inhibit phospholipase C activity independently of their role as Ca2+ chelators[1][2][3]. |
| 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]. |
