    • 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。

    • An apparatus and process for storing beads in a liquid medium and for draining and dispensing said beads essentially in the absence of said liquid medium is described. In one embodiment, the apparatus is designed so that the liquid medium in which the beads are stored can be captured in a separate compartment from the bead-containing compartment and the beads can be delivered without the liquid medium when the apparatus in inverted. This apparatus is designed so that the liquid medium will join with the beads for storage in the bead-containing compartment when the apparatus is upright. In another embodiment, the apparatus includes a bottle with a removable, threaded inner container which is used to drain the liquid medium from the beads prior to attachment to a separate bead dispenser.
    • 描述了一种用于在液体介质中存储珠子并且用于在没有所述液体介质的情况下基本上排出和分配所述珠子的装置和方法。 在一个实施例中,设备被设计成使得其中存储珠的液体介质可以被捕获在与包含珠的隔间的单独隔室中,并且当设备倒置时,珠可以被输送而没有液体介质。 该设备被设计成使得当设备直立时,液体介质将与珠接合以存储在包含珠的隔间中。 在另一个实施例中,该装置包括具有可移除的带螺纹的内部容器的瓶子,其用于在连接到单独的珠子分配器之前从珠粒中排出液体介质。
