BAPTA, tetrapotassium salt

CAS 73630-08-7

BAPTA (1,2-bis(o-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid) is a water-soluble and cell-impermeable calcium chelator. It has high selectivity to calcium. BAPTA is a calcium-specific aminopolycarboxylic acid. The presence of four carboxylic acid functional groups makes possible the binding of two calcium ions. The extensive flexibility of the carboxylate ligands is critical to the coordination of calcium and other metal ions.
