Summary

Automatic Translation

Vi præsenterer her, en protokol for at studere den molekylære mekanisme af proton translokation over lipid membraner af enkelt Liposomer, ved hjælp af cytokrom bo3 som et eksempel. Kombinere elektrokemi og Fluorescens mikroskopi, pH-ændringer i lumen af enkelt blærer, der indeholder én eller flere enzym, kan registreres og analyseres individuelt.
