Description

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.
