据统计约 30% 细胞系被交叉污染或错误辨识,因使用了交叉污染或错误辨识的细胞而导致研究结论错误、结果不可重复、临床细胞治疗灾难性后果……,这浪费大量时间、精力和金钱。Everything was going along fine until they discovered their HeLa cell line expressed Y chromosome markers因此近年 NIH、ATCC、Nature 和 Science 等对此多次发出呼吁,要求研究者对细胞进行鉴定。STR 基因
基因组 DNA 为模板进行 PCR 扩增,电泳确认 PCR 产物大小,对大小正确的产物进行测序,如测序结果与理论序列一致,则确认该基因编辑小鼠模型为正确重组模型。 TIPS 双臂 PCR 产物需测通:我们在实践中发现,即使 Donor 序列完全正确,部分鼠会存在突变或片段缺失的情况,我们推测是细胞在 Donor 重组前或过程中对 Donor 发生了编辑或重组后结构不稳定等原因所致,所以只对 Donor 各个部分接头测序是不严谨的,建议测通。 下面以 CKO 模型鉴定为例说明双臂 PCR 鉴定
短串联重复序列(short tandem repeat,STR),又称为微卫星DNA ,重复单位为2-6bp,重复次数10~60多次,在DNA复制过程中的滑动、复制、修复过程中滑动链与互补链的碱基错配,从而导致一个或几个重复单位的缺失或插入,形成STR的多态性,主要应用于遗传连锁图谱分析、家系鉴定、身份认证等领域,同时也是鉴定细胞株被错误识别和交叉污染的主要工具。细胞株被错误识别及交叉污染的现象还是比较普遍的,虽然科研工作者使用各种各样的传统方法来鉴定细胞,但细胞交叉污染的问题却有增无减
