Abstract

The invention provides a fast and economical immunofluorescence method based on cell slides, which belongs to the technical field of cell and molecular biology, and includes preparation of cell slides and immunofluorescence staining, wherein the steps of preparing cell slides are: purifying and washing PGCs cells Place the slides on amino-modified glass slides and fix them to obtain cell slides; the steps of immunofluorescence staining are as follows: cover the slides face down on the blocking solution; add antibodies dropwise, incubate and wash; add antibody-labeled slides dropwise Anti-fluorescent fading agent, absorb excess anti-fluorescent fading agent around the slide, then observe the fluorescence and take pictures under a fluorescent microscope. The immunofluorescence method of the present invention is easy to operate, easy to master, can accurately locate the position of the antigen and display the relative amount, and the preparation method of the cell slides used has the advantages of simple materials, cost saving, good slide effect, uniform distribution of cells after slides, It has the advantages of convenient operation and time saving.

Description

technical field [0001] The invention belongs to the technical field of cell and molecular biology, and in particular relates to an immunofluorescence method based on cell slides. Background technique [0002] Duck Virus Hepatitis (DVH) is an acute and highly fatal infectious disease of ducklings caused by duck hepatitis virus. Opistonus, hepatomegaly and a large number of hemorrhagic spots can be seen in autopsy, which is one of the main diseases that endanger the duck industry. The disease can be preliminarily diagnosed based on epidemiology, typical symptoms and lesions, that is, the onset and death of ducklings, acute onset, rapid death, concentrated death time, and liver swelling with obvious bleeding points or spots. Laboratory tests are still needed to confirm the diagnosis. Currently, laboratory tests mainly include virus isolation and preliminary identification, neutralization test, agar immunodiffusion test, indirect hemagglutination test, dot immunogold filtration...
