Problems solved by technology

[0003] At present, the detection methods of rabbit plague virus antibody include hemagglutination method, RT-PCR method, and enzyme-linked immunosorbent assay. Among them, RT-PCR method and enzyme-linked immunoassay method require large-scale instruments and professionals, while hemagglutination method is simple to operate, but Human red blood cells are needed, which are expensive and not suitable for long-term storage. This study uses the principle of immune colloidal gold to develop a rapid detection card preparation method for rabbit plague virus antibodies, which reduces the time for rapid, sensitive and accurate detection of rabbit plague virus antibodies. and cost

Abstract

The invention relates to a rabbit pestivirus antibody rapid detection card and a preparation method thereof. The preparation method comprises the following concrete steps: (1) preparing an anti-rabbit-pestivirus VP60 monoclonal antibody, concretely performing immunization program, cell fusion, hybridomas screening and cloning, and antibody preparation and purification; and (2) preparing the rabbit pestivirus antibody rapid detection card, concretely decocting a colloidal gold solution, marking the anti-rabbit-pestivirus VP60 monoclonal antibody, processing a colloidal-gold pad, processing a sample pad, and determining C and T lines. The rabbit pestivirus antibody rapid detection card is capable of rapidly, sensitively and accurately detecting rabbit pestivirus antibody, and overcomes the problems that domestic rabbit pestivirus antibody detection mainly employs erythrocyte hemagglutination and ELISA detection.

Description

technical field [0001] The invention relates to a rapid detection card for rabbit plague virus antibody and a preparation method thereof, belonging to the technical field of immune detection. Background technique [0002] Rabbit plague is an acute, febrile, septic and devastating infectious disease caused by a virus. It can occur all year round, and all kinds of rabbits are susceptible. Young rabbits and adult rabbits over 3 months old have the highest morbidity and mortality (up to 95%). [0003] At present, the detection methods of rabbit plague virus antibody include hemagglutination method, RT-PCR method, and enzyme-linked immunosorbent method. Among them, RT-PCR method and enzyme-linked immunoassay method require large-scale instruments and professionals, while hemagglutination method is simple to operate, but Human red blood cells are needed, which are expensive and not suitable for long-term storage. This study uses the principle of immune colloidal gold to develop ...
