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

Cell－Death－Differ：前列腺癌恶化标志
前列腺癌是近年来导致西方国家男性死亡的严重癌症之一，扩散性疾病的患者治疗情况也不够乐观。血清中的前列腺特意抗原（PSA）是用于癌症检测的分子标记，但是对于癌症的恶化PSA并不能够达到准确的预测，因此找到一个更加合适的分子标记对于前列腺癌的中期诊断十分重要。另一方面，由于前列腺癌的异质性，至今还没

Cell－Death－Dis：中风患者遭受脑损伤的新机制
近日，研究人员发现中风患者遭受脑损伤的机制，并正在寻找药物来阻止它。 当供应到大脑的血液被部分切断时中风发生，但对于存活者而言更严重的伤害是记忆和其他认知功能伤害，这些记忆和其他认知功能伤害常常实际上由血液供应恢复后的几小时或几天内“氧化应激”生成过多所引起的。 从Leeds大学和中国浙江大
