Problems solved by technology

Currently, the detection methods used in the diagnosis of SVV have many procedures and complicated operation steps, and it takes at least one day for the detection to obtain the results. Therefore, it is impossible to realize the instant detection of a large number of samples in the event of an outbreak

Abstract

The invention discloses a double antibody sandwich ELISA kit used for Seneca viral antigen detection and application thereof. The kit comprises a Seneca viral guinea pig anti-IgG enveloped elisa plateand an HRP marked Seneca viral rabbit anti-IgG. The HRP marked rabbit anti-IgG is used for replacing primary antibodies and secondary antibodies in traditional ELISA, so that the operating steps aresimplified. Simultaneously, the SVV guinea pig anti-IgG is enveloped to the surface of a solid-phase carrier by changing an enveloping stabilization technology, the preparation technology of an enzyme-labeled antibody diluent is changed, an enzyme-labeled antibody working solution can be stored stably without changing the activity and valence, and a double antibody sandwich ELISA kit for SVV antigen specific detection and a detection method thereof are established. The vacancy of making up SVV ELISA antigen detection is proposed, the problem that existing virus separation and detection for SVVantigens are low in repeatability and sensitivity and complex in operational program is overcome, and effective technical means is provided for SVV antigen detection.

Description

technical field [0001] The invention relates to a virus detection kit and its application, in particular to a double-antibody sandwich ELISA kit for Seneca virus antigen detection based on Seneca virus (Seneca Valley virus, SVV) specific enzyme-labeled antibody technology and its application. The invention belongs to the technical field of biological detection. Background technique [0002] SVV, also known as Seneca Valley virus (SVV), is no stranger to U.S. swine herds. Over the past 30 years, nearly 20 cases of SVV infection have been identified. In the United States, SVV is commonly associated with idiopathic swine vesicular disease. SVA has been reported worldwide, including Canada, Australia, Italy, New Zealand, and Brazil. SVV is a non-enveloped, single-stranded RNA virus belonging to the picornaviridae family like porcine foot-and-mouth disease (FMD) and porcine vesicular virus. It may be the causative agent of porcine idiopathic vesicular disease, but this has n...
