    • An apparatus is disclosed for enzyme detection that is particularly well suited for high performance liquid chromatography. The apparatus is basically a flow-through enzyme detector that is capable of maintaining zero-order reaction kinetics with respect to substrate during enzyme detection and this results in a linear accumulation of product that can be readily measured to provide a dependable readout of detected enzymes. A sample in liquid form that may include one or more enzymes is coupled through a separation column to separate the enzymes, after which a reaction causing substrate is added and the resulting mixture is caused to flow through a reaction chamber, reaction products then being detected with the readout therefrom indicating the detected enzymes. The dimensions of the reaction chamber are dependent upon flow rates and must be selected to allow the mixture to remain in the chamber for a preselected reaction time. In addition, the chamber and packing material therein are selected to assure minimization of chromatographic profile distortion by band spreading as well as preventing separation of the components of the mixture passing therethrough. To this end, the chamber and packing material within the chamber must be of non-porous material, inert to proteins to be detected, and must assure even flow conditions.
    • 公开了用于酶检测的装置,其特别适用于高效液相色谱法。 该装置基本上是一种流通酶检测器,其在酶检测期间能够保持相对于底物的零级反应动力学,并且这导致可以容易地测量以产生检测到的酶的可靠读数的产物的线性积累。 可以包括一种或多种酶的液体形式的样品通过分离柱偶联以分离酶,然后加入反应引发的底物并使所得混合物流过反应室,然后用反应产物检测反应产物 其读数指示检测到的酶。 反应室的尺寸取决于流速,并且必须选择以允许混合物保留在室中预选的反应时间。 此外,其中的室和包装材料被选择为通过带扩展确保最小化色谱分布畸变,并且防止通过其中的混合物的组分的分离。 为此,腔室中的腔室和包装材料必须是无孔材料,对待检测的蛋白质是惰性的,并且必须确保均匀的流动条件。

    • A method for analysis of hemoglobin variants by high speed liquid chromatography and, more particularly, by ion-exchange chromatography. Through the use of high flow rates and pressures, the hemoglobin variants can be rapidly forced through the separation column to thus enable rapid analysis. A bonded phase inorganic support column is utilized for separation of the hemoglobin variants with the profiles thereof then being obtained. The bonded phase support preferably includes ion-exchange groups bonded through a carbohydrate intermediate to controlled porosity glass. A pair of different columns may be utilized to separate the hemoglobin variants with one of the columns being an anion-exchanger, and more particularly, a diethylaminoethanol glycophase, controlled porosity glass column, with the other column being a cation-exchanger, and more particularly, a carboxymethyl glycophase, controlled porosity glass column. The hemoglobin profiles obtained from such a pair of columns are different and the combination of chromatographic data obtained identify the particular hemoglobin variants and can thus be utilized for diagnosis purposes.
    • 用于通过高速液相色谱分析血红蛋白变体的方法,更具体地,通过离子交换色谱分析方法。 通过使用高流量和压力,血红蛋白变体可以快速强制通过分离柱,从而实现快速分析。 使用键合相无机载体柱用于分离血红蛋白变体,然后获得其轮廓。 键合相载体优选包括通过碳水化合物中间体键合到受控多孔玻璃上的离子交换基团。 可以使用一对不同的柱来分离血红蛋白变体,其中一个柱是阴离子交换剂,更具体地,二乙基氨基乙醇糖相,控制孔隙率玻璃柱,另一个柱是阳离子交换剂,更特别地 ,羧甲基糖相,控孔孔玻璃柱。 从这样的一对柱获得的血红蛋白谱是不同的,并且所得到的色谱数据的组合识别特定的血红蛋白变体,因此可以用于诊断目的。
