Abstract

The bumetanide-sensitive Na-K-Cl co-transport system in ferret red cells produces net movement of 1Na:1K. Tracer studies have misleadingly suggested a stoichiometry of 2Na:1K probably because the transporter mediates substantial Na-Na exchange in these cells.

摘要

雪貂红细胞中对布美他尼敏感的钠-钾-氯共转运系统产生1个钠:1个钾的净移动。示踪研究错误地表明其化学计量比为2个钠:1个钾，这可能是因为该转运体在这些细胞中介导了大量的钠-钠交换。
