BAPTA, AM *CAS 126150-97-8*


Molecular weight
BAPTA AM is cell-permeable version of BAPTA (1,2-bis(o-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid), a cell-permeable calcium chelator. This BAPTA derivative is used for adjusting calcium concentrations in cells and tissues. 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.
