BAPTA/AM [1,2-Bis(2-aminophenoxy)ethane-N,N,N′,N′-tetraacetic acid tetrakis(acetoxymethyl ester)] is a non-fluorescent, membrane-permeable form of BAPTA. Whereas the BAPTA, Free acid (sc-201508) is not cell permeable and is only useful for manipulating extracellular Ca2+ levels, BAPTA/AM can be used with a wide variety of cells, where it is hydrolyzed by cytosolic esterases and trapped intracellularly. Experiments have shown that BAPTA/AM abolishes vitamin D3-induced increase in intracellular Ca2+, and may induce inactivation of protein kinase C. BAPTA/AM has also been shown to inhibit thapsigargin-induced apoptosis in rat thymocytes. BAPTA/AM is a high quality and sensitive compound for calcium signaling studies, investigation of signal transduction and apoptotic cascades, and neuroscience research.
