BAPTA free acid was identified as the main metabolic product of 1,2-bis(2-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid tetra(actoxymethyl ester) (BAPTA-AM), a neuroprotective agent in cerebral ischemia, in rats. In this paper, liquid chromatography-ultraviolet (LC-UV) and mass spectrometry/mass spectrometry (LC-MS/MS) methods were employed for the

In vivo light-induced and basal hydrolysis of phosphatidyl inositol 4,5-bisphosphate (PIP2) by phospholipase C (PLC) were monitored in Drosophila photoreceptors using genetically targeted PIP2-sensitive ion channels (Kir2.1) as electrophysiological biosensors for PIP2. In cells loaded via patch pipettes with varying

Sustained alteration in [Ca(2+)]i triggers neuronal death. We examined morphological and signaling events of Ca(2+)-deficiency-induced neuronal death. Cortical cell cultures exposed to 20 microM 1,2-bis(2-aminophenoxy)ethane-N,N,N',N'-tetraacetic acid (BAPTA-AM), an intracellular calcium chelator, underwent neuronal apoptosis within 12 h that was evident

We designed Calcium Rubies, a family of functionalizable BAPTA-based red-fluorescent calcium (Ca(2+)) indicators as new tools for biological Ca(2+) imaging. The specificity of this Ca(2+)-indicator family is its side arm, attached on the ethylene glycol bridge that allows coupling the

The SNARE protein vti1a is proposed to drive fusion of intracellular organelles, but recent data also implicated vti1a in exocytosis. Here we show that vti1a is absent from mature secretory vesicles in adrenal chromaffin cells, but localizes to a compartment
