    • An ion exchange method and kit for the separation of hemoglobin A.sub.1c from other hemoglobin components in a sample of human blood. The sample is lysed, then used to impregnate a weak cation exchanger. Two buffer solutions are then passed through the column in succession, the first having an alkali metal ion concentration of from about 0.02M to about 0.05M and the second having an alkali metal ion concentration of from about 0.06M to about 0.11M. The second eluate contains substantially all of the hemoglobin A.sub.1c and substantially none of the other hemoglobin components in the original sample. Analysis of the second eluate thus provides a reliable indication of the long-term glucose level in the blood of a patient, and hence the patient's ability to regulate the quantity of glucose ingested. The hemolysate with the Schiff base precursor is introduced directly to the chromatographic column.
    • 用于将血红蛋白A1c与人血样品中的其他血红蛋白成分分离的离子交换方法和试剂盒。 将样品裂解,然后用于浸渍弱阳离子交换剂。 然后将两个缓冲溶液依次通过柱,第一个碱金属离子浓度为约0.02M至约0.05M,第二种碱金属离子浓度为约0.06M至约0.11M。 第二洗脱液基本上含有原始样品中的所有血红蛋白A1c和基本上没有其他血红蛋白成分。 因此,第二洗脱液的分析提供了患者血液中长期葡萄糖水平的可靠指示,因此提供了患者调节摄取的葡萄糖量的能力。 将含有席夫碱前体的溶血液直接引入色谱柱。
