Funktionelle Charakterisierung von Na<sup> +</sup> / H<sup> +</sup> Wärmetauscher von intrazellulären Kompartimente Mit Proton-Tötung Selection man sie an der Plasmamembran Express
The first part of this article shows how to select mutant cell lines expressing vesicular Na+/H+ exchangers at their plasma membrane. The second part provides protocols based on intracellular pH measurements and fast ion uptake, which are used to determine the ion selectivity and the kinetic parameters of these exchangers.
