Abstract
39K n.m.r. was used to detect and quantify K+ within human erythrocytes. A shift reagent consisting of an anionic complex of dysprosium(III) with sodium tripolyphosphate permitted a distinction to be made between K+ inside and outside erythrocytes. Intracellular K+ concentrations determined by this method were similar to values obtained by flame photometry.
摘要
利用39K核磁共振技术检测和定量人体红细胞内的钾离子。一种由镝（III）与三聚磷酸钠形成的阴离子配合物组成的位移试剂，能够区分红细胞内外的钾离子。用这种方法测定的细胞内钾离子浓度与火焰光度法测得的值相似。
