BackgroundPan-Cytokeratin (AE1/AE3) contains two different clones, which label the majority of normal epithelia and carcinoma.Cytokeratins are a group of water soluble filament proteins, which are components of the cytoskeleton of the epidermis and other epithelial cells. Gelelectrophoretic investigation revealed 20 different Cytokeratins, characterised by different molecular sizes and pI-values. They can be subdivided into basic and acid subfamilies. The nomenclature according to Moll et al. (1982) is most commonly used. Basic cytokeratins (52-67 kD) and acid cytokeratins (40, 48, 50, 50", 56,5 kD) CK 1-8, 10, 14-16 and 19 according to the nomenclature by Moll (1982) .

评估细胞周期进程在许多研究领域都非常重要，传统的方法是将[3H]胸腺嘧啶核苷掺入S期细胞，然后通过闪烁计数或放射自显影来定量[3H], 以此来检测细胞增殖，但该技术流程耗时且费力，还有许多限制因素比如同位素污染处理和设备昂贵等问题。
