【摘要】 用过氧化物和超氧化物荧光探针DCFH-DA标记巨噬细胞后,在激光扫描共聚焦显微镜下,用最适发射波长为530nm的检测器1检测巨噬细胞内DCFH-DA的荧光强度变化,结果显示:检测器1可检测单个和多个巨噬细胞内DCFH-DA的荧光强度变化,经PMA作用后,巨噬细胞内DCFH-DA的荧光强度增强,而且各细胞增强的幅度不同。表明:通过检测DCFH-DA荧光强度变化可原位实时观察单个或多个活细胞内呼吸爆发的动态变化,PMA刺激巨噬细胞呼吸爆发作用,小鼠腹腔巨噬细胞存在异质性

【Abstract】 The peroxides and superoxides sensitive fluorescence probe DCFHDA was used to mark the macrophages.Then the variations of the fluorescence were detected with detector 1(optimum emission wavelength:530nm)of the laser scanning confocal microscope.The results showed,detector 1 detected the alterations of the fluorescence of DCFHDA.Treated with PMA,the fluorescence of the DCFHDA in every macrophage increased differently.The results indicated,by detecting the variations of the fluorescence of DCFHDA,the kinetic variations in respiratory burst of the attached live macrophages could be detected originally and continuously at the level of single cell or multicells.The PMA provoked respiratory burst of the macrophages.And the response in the macrophages to PMA is heterogeneous.
