近物所用新方法揭示电离辐射对线粒体DNA超螺旋构象影响
中科院近代物理研究所辐射生物医学研究组的科研人员研究发现，电离辐射能够引起显著的线粒体DNA超螺旋构象变化，这对进一步研究电离辐射对线粒体功能的影响具有指导意义。 线粒体DNA是人体细胞中唯一的核外遗传物质，线粒体DNA构象的变化可能通过影响线粒体功能而导致细胞命运的改变。目前
ELISpot实验操作流程
ELISPOT全名为酶联免疫斑点检测，英文：Enzyme-linked Immunospot Assay。它结合了细胞培养技术与酶联免疫吸附技术（即ELISA技术），能够在单细胞水平检测细胞因子的分泌情况。其技术原理，一句话概括就是：用抗体捕获培养中的细胞分泌的细胞因子，并以酶联斑点显色的方式将其表
