Abstract

The invention discloses a method for rapidly detecting retrovirus by a cell ultrathin section electron microscope. The method comprises the following steps: 1) collecting and fixing of a sample; 2) uranium acetate block dyeing; 3) dehydrating, permeating and polymerizing; 4) slicing, dyeing and detecting through a transmission electron microscope. Compared with a traditional method, the method hasthe advantages that the sample preparation efficiency is greatly improved, the traditional 5-7-day sample preparation period is shortened to 1 day, and an ultrathin slicing technology for rapidly detecting viruses becomes possible. Compared with a traditional virus detection method, the optimized ultrathin section electron microscope technology for detecting viruses has the advantage that the specificity, accuracy and detection efficiency of virus detection are greatly improved.
