Mitoplast patch clamp
Web30 apr. 2024 · In this study, we report, for the first time, the membrane current mediated by NCXm using the whole-mitoplast patch clamp technique. The recorded inward current is most likely mediated by the NCXm based on the Na + and Li + selectively, the requirement of Ca 2+ in the opposite membrane site, and the inhibition by CGP-37157. WebA. Schematic representation of the mitoplast preparation, patching of the mitoplast, and, finally, the patch-clamp experiment in the inside-out mode by means of the perfusion system. The...
