目的 :细胞培养中污染不可避免 ,应用电镜技术检测传代细胞中的细菌污染 ,既快速又准确。方法 :利用电镜 ,根据细菌的形态及其鞭毛、噬菌体等指标的其中一项判定细菌的污染。结果 :该检测结果为传代细胞的应用提供了可靠地保证 OBJECTIVE: The contamination in cell culture is unavoidable. The bacterial contamination in the passaged cells by electron microscopy is rapid and accurate. Methods: Using electron microscopy, bacterial contamination was judged according to one of the bacterial morphology and flagella, phage and other indicators. Results: The test results provide a reliable guarantee for the use of passaged cells
