Descrição geral

1,2-Bis(2-aminophenoxy)ethane-N,N,N′,N′-tetraacetic acid is a highly selective calcium chelating reagent. Effect of microinjected calcium-loaded 1,2-bis(2-aminophenoxy)ethane-N,N,N′,N′-tetraacetic acid (CaBAPTA) on cell-to-cell diffusion of carboxyfluorescein has been studied in staminal hairs of Setcreasea purpurea. It is reported to be a metabolite of 1,2-bis(2-aminophenoxy)ethane-N,N,N′,N′-tetraacetic acid tetra(acetoxymethyl ester) (BAPTA-AM) in rat urine.
pH 8.0 Highly selective calcium chelating reagent. Suitable for the spectrophotometric monitoring of Ca2+ levels

Aplicação

1,2-Bis(2-aminophenoxy)ethane-N,N,N′,N′′-tetraacetic acid was used for the spectrophotometric monitoring of Ca2+ levels. It may be used as chelator of cytosolic Ca²+ to investigate the effect of methoxychlor on cytosolic free Ca²+ concentrations and apoptosis in HA59T human hepatoma cells.
Highly selective calcium chelating reagent. Suitable for the spectrophotometric monitoring of Ca2+ levels

The effect of microinjected calcium-loaded 1,2-bis(2-aminophenoxy) ethane-N,N,N',N'-tetraacetic acid (CaBAPTA) on cell-to-cell diffusion of carboxyfluorescein (CF) was examined in staminal hairs of S. purpurea Boom. The CaBAPTA was microinjected into the cytoplasm of the staminal hairs either with CF or prior

Methoxychlor, an organochlorine pesticide, is thought to be an endocrine disrupter that affects Ca²⁺ homeostasis and cell viability in different cell models. This study explored the action of methoxychlor on cytosolic free Ca²⁺ concentrations ([Ca²⁺]i) and apoptosis in HA59T human

A role for increases in intracellular calcium (Ca2+) has been suggested in the pathophysiology of various forms of oxidant-mediated cell injury. In recent studies, we found that iron bound to the Pseudomonas aeruginosa siderophore, pyochelin, augments oxidant-mediated endothelial cell injury
