Detectionofapoptoticprocessinsituusingimmunocytochemical
1. INTRODUCTION Apoptosis was observed from invertebrates to lower and higher verterbrates, and intervenes both in physiological and in pathological states, such as normal cell turnover, embryogenesis, metamorphosis, thymic maturation and involution, neoplasm, etc. (1-4).Endonucleolysis is considered as the key biochemical event of apoptosis, resulting in cleavage of nuclear DNA into oligonucleosome-sized ......阅读全文

凋亡聚焦：选择合适的TUNEL分析
考虑检测方法 TUNEL分析一般采用显色法或荧光检测法。每一种都有其各自的优缺点，因此选择哪一种取决于您的需求。荧光检测感更为灵敏，但难以保留信号。由于成像时的光漂白，且随着时间的流逝，荧光信号会逐渐丧失。荧光信号也会有更高的背景问题，这要取决于组织类型。显色分析适用于组织切片，因为可以使

细胞凋亡检测方法介绍
细胞凋亡是指细胞在生长到一定阶段及某些生理过程中，会受到多因素和机制的严格调控而进入死亡。这是一个动态的过程,会涉及一系列复杂的生化反应, 是一个需要酶参与的级联反应,同时也涉及不同基因的表达及调控、信号传导。其中有几项生理过程能被用来检测凋亡的发生，因此多参数分析法对于准确检测这一过程十分
