一般描述

戊二醛是一种饱和二醛，广泛用作化学杀菌剂。戊二醛溶液由固定效率不同的单体和聚合体混合而成。 

应用

戊二醛溶液可用于：
  • 加入4-(2-羟乙基)-1-哌嗪乙磺酸(HEPES)缓冲液中，将浓缩的胞外囊泡(EV)固定在刀豆蛋白A上，进行扫描电镜(SEM)观察
  • 作为溶液组分，固定细胞并观察形态
  • 固定水溶液中的大肠杆菌，保持细菌细胞的表面形态

生化/生理作用

在生物医学研究中，戊二醛用于固定细胞，并可用于分析健康和病理红细胞。戊二醛广泛用于消毒各种医疗器械，包括肺活量计管、内窥镜、换能器、麻醉、呼吸治疗设备，以及一次性腹腔镜塑料套管的再利用。 

特点和优势

  • 应用高效安全，适配带透镜仪器、橡胶和塑料
  • 对金属无腐蚀性
  • 活化后保质期至少14天
