细胞增殖的检验方法：BrdU标记法
BrdU标记法1．细胞以1.5×105/ml细胞数接种于直径35ml培养皿中（内放置一盖玻片），培养1天，用含0.4％ FCS培养液同步化3天，使绝大多数细胞处于G0期。2．终止细胞培养前，加入BrdU（终浓度为30μg/L），37℃，孵育40min。3．弃培养液，玻片用PBS洗涤3次。4．甲醇/醋
细胞活性检测DNA合成增殖实验
BrdU检测法BrdU为胸腺嘧啶核苷（Thymine）的衍生物，可用于标记活细胞中新合成的DNA（细胞活性周期S期），BrdU可随着DNA复制进入子细胞，因此在加入BrdU后分裂增殖的细胞DNA都会带有BrdU标记，可通过抗BrdU单克隆抗体检测，借此检测细胞的增殖能力，但BrdU单克隆抗体检测过程

原代细胞周期测定的原理和BrdU方法
原理: 细胞周期:细胞一世代所经历的时间从一次细胞分裂结束到下一次分裂结束一个周期。细胞周期反应了细胞增殖速度。单个细胞的周期测定可采用缩时摄影的方法，但它不能代表细胞群体的周期，故现采用其他方法测群体周期。测定细胞周期的方法很多，有同位素标记法、细胞计法等。BrdU（5溴脱氧尿嘧啶核苷）加入培养基
姐妹染色单体交换(SCE)试验的基本内容
SCE是染色体同源座位上DNA复制产物的相互交换，SCE可能与DNA的断裂和重接有关，提示DNA损伤。SCE试验可分为体外试验、体内试验和体内、体外结合试验。体外SCE试验可采用贴壁生长的细胞，如CHO、V79、CHL等，也可用悬浮生长的细胞，如人外周血淋巴细胞。细胞在含5-溴脱氧尿苷(BrdU
