What is BAPTA-AM, Product A1076, and how is it used?
BAPTA-AM is a cell-permeant acetoxymethyl ester derivative of BAPTA (Product No. A4926), which is used as a chelator of intracellular Ca2+ stores. The acetoxymethyl ester derivative, which is an ester of the carboxylic acid groups in BAPTA, results in an uncharged molecule which allows it to penetrate cell membranes. Inside the cell, these groups are cleaved by nonspecific esterase activity resulting in the free acid form.
In what solvents is BAPTA-AM, Product A1076, soluble?
BAPTA-AM is soluble in dimethyl sulfoxide (DMSO) at 25 mg/mL. It is also soluble in acetonitrile at 0.5 mg/mL. It is best to use anhydrous DMSO, since it is known that moisture uptake by the DMSO can adversely affect the quality of the BAPTA-AM.
How would you recommend that I store my BAPTA-AM, Product A1076, solution?
Stock solutions of 1-10 mM can be prepared in anhydrous DMSO, divided into single-use aliquots, and stored desiccated and frozen at -20°C.
What are the shipping and storage temperatures for BAPTA-AM, Product A1076?
BAPTA-AM is shipped at ambient temperature. The recommended storage temperature, once received, is -20 °C.
What is the typical working concentration for BAPTA-AM, Product A1076?
The typical final working concentrations for cell loading is in the range of 1 to 10 micromolar. It is best to find literature references dealing with your application for more information on the amounts to use.
