Several parameters of stimulation of individual lymphocytes are measured simultaneously by flow-cytofluorometry after differential staining of cellular DNA and RNA with the metachromatic fluorescent dye acridine orange. The method provides a means of analyzing the progression of stimulated cells through the cell cycle (G1, S and G2 + M), in addition to measuring the accumulation of RNA per cell; the RNA parameter is useful in distinguishing G1 from G0 cells. The multiparameter analysis may be of unique value in discriminating cases where the transcriptional and proliferative responses of lymphocytes to stimulants are not correlated.
在用异染荧光染料吖啶橙对细胞DNA和RNA进行差异染色后,通过流式细胞荧光术同时测量单个淋巴细胞的几个刺激参数。该方法除了可测量每个细胞中RNA的积累外,还提供了一种分析受刺激细胞在细胞周期(G1、S和G2+M)中的进展情况的方法;RNA参数有助于区分G1期细胞和G0期细胞。在区分淋巴细胞对刺激物的转录反应和增殖反应不相关的情况时,多参数分析可能具有独特的价值。
