General description

BAPTA-AM inhibits free radical-mediated toxicity, enhances apoptosis in non-neuronal cells and protects neurons from ischemic damage. It regulates ion channels and blocks neuronal Ca2+-activated K+ channel currents. BAPTA-AM maintains intracellular Ca2+ homeostasis.

Application

BAPTA-AM has been used :
  • to reduce the elevation of cleaved caspase-3
  • to block cell death, inhibit ROS (reactive oxygen species) production and inhibit caspase-8 activation
  • to exclude the effect of changes in intracellular Ca2+ ([Ca2+]i) concentration during seizure induction
  • to eliminate the increase of [Ca2+]i induced by 6-hydroxydopamine (6-OHDA)

Biochem/physiol Actions

Selective chelator of intracellular Ca2+ stores.

Linkage

Membrane-permeable form of BAPTA.
