背景资料

BAPTA (Item No. 11706) is membrane-impermeable calcium chelator that binds extracellular calcium ions (Kd = 0.11 μM), with selectivity over magnesium ions or protons.{22804,23059} BAPTA and its derivatives can also be used as calcium indicators, since the absorption maximum for BAPTA changes when it is complexed with calcium (absorption maxima free/complexed = 254/274 nm, emission maxima free/complexed = 363/363 nm).{25230} BAPTA-acetoxymethyl ester (BAPTA-AM) is a cell permeable analog of BAPTA that binds calcium only after the acetoxymethyl group is removed by cytoplasmic esterases.{25228} It is commonly used at 10-100 μM to evaluate the role of intracellular calcium in cell signaling.{25229,25228,25226,25225} It can also be used in animals.{25228} BAPTA-AM also inhibits voltage-gated potassium (Kv) channels, including Kv1.3, Kv1.5, and Kv11.1 (Ki = 1.45, 1.23, and 1.30 μM, respectively).{25227}
