MULTIPLE ASSAYS OF CELL SPECIMENS

摘要

A method for increasing the accuracy and the types of data measurements of laser scanned dye stained cells, in a single sample, by means of multiple assays, utilizing cell positions as a factor in merging da ta measurements. Change in lasers, use of different cell dye stains and different treating reagents provide additional data regarding cells of t he sample and fixing of cell positions in the first assay permits merging of the data obtained in subsequent assays. The laser scanning cytometer (100) includes laser optics (102) which irradiates cells positioned on a slide (105) with a laser beam (101) to produce fluorescence and light scatter from the cells. Computer control (106) serves to control the slide position and the laser beam (101).
