用于检测细菌及真菌死活状态的荧光染色试剂、制备方法及用途
摘要：
本发明公开了一种用于检测细菌及真菌死活状态的荧光染色试剂、制备方法及用途，其中，该荧光染色试剂包括染料分子，该染料分子可通过在聚乙二醇分子两端分别化学连接胆固醇分子和荧光分子获得。本发明对细菌或动物细胞的毒性低，几乎无生物毒性，能够实现对细菌和真菌死活状态的长时间检测；另外，本发明的试剂具有良好的水溶性。
摘要（英）：

The invention discloses a fluorescent dyeing reagent for detecting a bacterium and fungus survival state and its preparation method and use. The fluorescent dyeing reagent comprises dye molecules. The dye molecule is prepared through respectively connecting a cholesterol molecule and a fluorescent molecule to two ends of a polyethylene glycol molecule. The fluorescent dyeing reagent has low bacterium or animal cell toxicity, has little biotoxicity and realizes long-term detection of a bacterium and fungus survival state. The fluorescent dyeing reagent has good water solubility.
