CELLCYCLEANALYSIS

PROPIDIUM IODIDE: The most commonly used dye for DNA content/cell cycle analysis is PROPIDIUM IODIDE (PI). It can be used to stain whole cells or isolated nuclei. The PI intercalates into the major groove of double-stranded DNA and produces a highly fluorescent adduct that can be excited at 488 nm with a broad emission centred around 600 nm. Since PI can also bind to double-stranded RNA, it is necessary to treat the ......阅读全文

玉米Proline responding 1(pro1)突变在蛋白合成和细胞周期调控

  上海大学生命科学学院、上海市能源作物育种及应用重点实验室的研究人员证实,玉米Pro1基因(Zm P5CS2)的突变造成了突变体细胞中脯氨酸(proline)合成受阻,从而导致proline积累的减少。突变体中proline的缺乏引起了相应的转运RNA(tRNApro AGG)空载形式(uncha

FCM对外周白细胞的免疫荧光分析

外周血是临床检验中的重要标本。FCM分析外周白细胞的主要目的是了解各种白细胞的数目与分群情况。这些数字的变化与临床的某些疾病有一定的关系。近年来,由于多种识别白细胞膜表面抗原的单克隆抗体的发现,以及对这些单克隆抗体的直接或间接荧光标记物的出现,使得利用FCM的荧光组织化学分析获得被测细胞的多指标的更
