Figure 1.Determination of apoptosis in transiently transfected murine [beta] tumor cells. (A) The number of apoptotic [beta]HC 13T tumor cells (% apoptosis) in the total transfected eGFP-positive population is shown. Co-transfections of pEGFP and the plasmids as indicated were carried out using LipofectAMINE as described in the text. Apoptotic cells were measured by flow cytometric analysis either using PI stain......閱讀全文

細胞凋亡（apoptosis）的檢測1
細胞凋亡（apoptosis）是一種由基因控制的細胞自主性死亡方式。其發生誘因及形態學特征均有別于壞死，與人類免疫系統的發生發展、神經組織發育、器官的形成、腫瘤的發生發展等諸多生物學現象之間有著密切聯系，并且是免疫應答過程中免疫細胞的殺傷機制之一。細胞凋亡的檢測技術已成為免疫學檢測的一個重要內容。凋
