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 solid phase competition ELISA kit for detecting Seneca valley virus antibody, and applications thereof, wherein the kit comprises Seneca valley virus inactivated antigen-coated enzyme label plate and HRP-labeled Seneca valley virus rabbit anti-IgG. According to the present invention, the primary antibody and the secondary antibody in the traditional ELISA are replaced with the HRP-labeled rabbit anti-IgG so as to simplify the operation step; by changing the coating stabilization process, the surface of the solid phase carrier is coated with the SVV inactivated antigen, such that the enzyme-labeled antibody diluent preparation process is changed, the enzyme-labeled antibody working liquid can be stably stored without the change of the activity and the titer, and the solid phase competition ELISA kit for the specific detection of the SVV antibody, and the detection method thereof are established; and with the kit, the blank in the SVV ELISA antibody detection ismade up, the problems of low repeatability, low sensitivity and cumbersome operation procedures in the SVV antibody detection in the existing VNT detection are overcome, and the effective technical means is provided for the SVV antibody detection.

Description

technical field [0001] The invention relates to a virus detection kit and its application, in particular to the establishment of a SVV solid-phase competitive ELISA antibody detection kit based on 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 not been...
