    • An automated system for rapid sequential photometric analysis of a collection of double fluorochrome stained lymphocyte specimens, useful for antibody screening or lymphocytotoxicity analysis. The specimens are sequentially alternately irradiated with light of two distinguishable wavelengths, producing fluorescence at two distinguishable wavelengths. The fluorescent emission light intensity for each irradiation of each specimen is measured using a photometer and computer. The computer controls the synchronization of the irradiation through alternately selected condenser sets with the sequential movement of specimens into the optical path of the irradiating and detected light, and calculates the quotient of the light intensities emitted from each specimen at the two selected fluorescent light wavelengths. These quotients are compared against a control ratio (for lymphocytotoxicity analysis) to classify the specimen. Also described is a method of preparing specimens for such analysis, which requires that a complement be added to the first staining solution after the latter is applied to the specimens, then this combination agitated, and then the second staining solution added and the specimen incubated.
    • 一种用于快速顺序光度分析双重荧光染色淋巴细胞标本的自动化系统,可用于抗体筛选或淋巴细胞毒性分析。 用两个可辨别的波长的光顺序地交替地照射样品,在两个可区别的波长处产生荧光。 使用光度计和计算机测量每个样品的每次照射的荧光发射光强度。 计算机通过交替选择的聚光器组来控制照射的同步,同时将样品顺序移动到照射和检测光的光路中,并计算在两个选定的荧光波长处从每个样品发射的光强度的商。 将这些商与对照比(用于淋巴细胞毒性分析)进行比较以对样品进行分类。 还描述了制备用于这种分析的样品的方法,其要求在将样品应用于样品后将补体添加到第一染色溶液中,然后将该组合搅拌,然后加入第二染色溶液并将样品孵育。
