用基于熒光的方法來評價細胞的增殖
簡介體外監測細胞的增殖對于基礎研究和應用研究都極有價值并有潛力應用在臨床領域。 3H-thymidine 或 5-bromo-deoxyuridine (BrdU, 胸苷的類似物 ) 摻入法是確定培養細胞的增值率的傳統方法，這主要是因為幾乎沒有更方便的替代方法。因而人們投入了大量的精力來開發一種快速

BrdU標記法檢測細胞增殖的原理
細胞增殖能力是測定物質毒性、評估藥物安全、評價細胞活力的重要指標之一，被廣泛應用于分子生物學、腫瘤生物學、免疫學和大規模藥物篩選等研究領域。目前檢測細胞增殖能力的方法主要分為兩類：一類是直接測定進行分裂的細胞數來評價細胞增殖能力，如Ki67、BrdU以及EdU細胞增殖檢測等；一類是通過測定活性細胞數
細胞周期測定實驗——BrdU滲入法
實驗方法原理細胞周期指細胞一個世代所經歷的時間。從一次細胞分裂結束到下一次分裂結束為一個周期。細胞周期反應了細胞增殖速度。?單個細胞的周期測定可采用縮時攝影的方法，但它不能代表細胞群體的周期，故現多采用其他方法測群體周期。?BrdU（5-溴脫氧尿嘧啶核苷）加入培養基后，可做為細胞DNA復制的原料，經
