AlexaFluor®488AnnexinV／DeadCellApoptosisKit
实验概要Apoptosis is a carefully regulated process of cell death that occurs as a normal part of development. Inappropriately regulated apoptosis is implicated in disease states, such as Alzheimer’s disease and cancer. Apoptosis is distinguished from necrosis, or accidental cell death, by characteristic morphological and biochemical changes, including compaction and fragmentation of th......阅读全文

细胞凋亡（apoptosis）的检测1
细胞凋亡（apoptosis）是一种由基因控制的细胞自主性死亡方式。其发生诱因及形态学特征均有别于坏死，与人类免疫系统的发生发展、神经组织发育、器官的形成、肿瘤的发生发展等诸多生物学现象之间有着密切联系，并且是免疫应答过程中免疫细胞的杀伤机制之一。细胞凋亡的检测技术已成为免疫学检测的一个重要内容。凋
