TRIPLE LASER-MULTI PARAMETER FLOW CYTOMETRY FOR STUDY OF TUMOR CELL KINETICS

已经开发了三重激光流式细胞仪， 免疫荧光标记技术可用于 细胞动力学研究。 三束不同波长的激光 使长度与穿过肿瘤细胞流的肿瘤细胞流相交， 石英比色皿，从而可以获得多参数信号。 这些 信号由专门的电子设备处理，然后通过 PDP 11电脑 简化的光学系统增加了光探测能力 效率提高了一个数量级。 该系统目前正在使用 研究一种单细胞原生动物锥虫 克氏锥虫病的病原体。 电子单元体积 系统中增加了辅助双变量分析的功能 克氏锥虫的荧光数据。

A triple laser flow cytometer has been developed so that various immuno-fluorescent labeling techniques may be employed for the investigation of cell kinetics. Three laser beams at different wave lengths are made to intersect a tumor cell flow stream passing through a quartz cuvette so that multi-parameter signals may be obtained. These signals are processed by specialized electronics and then analyzed by means of a PDP 11 computer. Simplified optics have increased light detection efficiency by an order of magnitude. The system is currently being used for the investigation of a unicellular protozoon known as trypanosoma cruzi, the causative agent of Chagas disease. Electronic cell volume capability has been added to the system to assist in the bivariate analysis of trypanosoma cruzi fluorescence data.
