BAPTA Chemical Properties,Usage,Production

Description

BAPTA free acid (85233-19-8) is a selective extracellular Ca2+ chelator. It is a widely used calcium sponge for chelating Ca2+?outside of intact cells.1 It’s a useful tool to probe the involvement of extracellular Ca2+ in cellular signaling.2,3 Non-cell-permeable.

Chemical Properties

White Solid

Uses

Highly selective calcium chelating reagent. Suitable for the spectrophotometric monitoring of Ca2+ levels.

Uses

BAPTA is a highly selective calcium chelating reagent. Lipophilic diesters of the chelating agent 1,2-Bis(2 aminophenoxy)ethane-N,N,N',N'-tetraacetic acid (BAPTA) are used for inhibition of proteolytic activities of certain metalloproteinases, calpain and TACE.

Uses

As calcium chelator; 19F labelled forms for measurement of intracellular calcium.

Definition

ChEBI: A polyamino carboxylic acid in which bis(carboxymethyl)nitrilo groups are bonded to C-2 and C-2' of 1,1'-[ethane-1,2-diylbis(oxy)]dibenzene.

General Description

In nature 1,2-Bis(2-Aminophenoxy)ethane-N,N,N′,N′-tetra acetic acid (BAPTA) is a main metabolic product of BAPTA -AM (BAPTA-tetra(actoxymethyl ester), a neuro protective agent in cerebral ischemia, in rats.BAPTA is an intercellular Ca2+ chelator.

Biological Activity

Selective calcium chelator.

storage

Store at +4°C
