作者报告免疫过氧化物酶法的两种新的应用:逐个细胞表面免疫球蛋白(SIg)定量和B淋巴细胞的自动识别。第一种用法:以Zeiss显微分光光度计和Leitz分类板作了逐个细胞SIg定量。6例慢性淋巴细胞白血病(CLL)每个细胞的活性变动范围位于100～200单位之间。对照的4名正常人的活性位于400～2900单位之间、这些结果与在CLL所见者显然不同。CLL细胞表面密度的范围为100～1200单位,其高峰点为100～300单位,而正常人之细胞表面密度为400～2900单 The authors report two new uses of the immunoperoxidase method: quantitation by cell surface immunoglobulin (SIg) and automatic recognition of B lymphocytes. The first usage: Quantitative SIg by cells using a Zeiss microscope and a Leitz classification plate. 6 cases of chronic lymphocytic leukemia (CLL) per cell activity range of 100 to 200 units. Four controls normalized their activity between 400 and 2900 units and these results are clearly different from those seen in CLL. CLL cell surface density in the range of 100 to 1200 units, the peak point of 100 to 300 units, while the normal cell surface density of 400 to 2900 single
