Overview

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 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. Has also been shown to inhibit thapsigargin-induced apoptosis in rat thymocytes. This product is a high quality and sensitive compound for calcium signaling studies, investigation of signal transduction and apoptotic cascades, and neuroscience research.
A membrane-permeable form of BAPTA;Selective chelator of intracellular Ca2+ stores.

Note

Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour. Refer to SDS for further information. For more information on AM esters please visit our AM esters FAQ page . Need more advice on solubility, usage and handling?
