Abstract

The invention provides a monoclonal antibody against smooth Brucella (Brucella) lipopolysaccharides (sLPS), and preferably provides 14F4. Cross reaction tests show that the monoclonal antibody 14F4 has no cross reaction with Escherichia coli (O:157), Salmonella Dublin (C79-86) whole thallus and the LPS. On the basis, a competitive ELISA (c-ELISA) test method using the monoclonal antibody 14F4 as a competition antibody is established, and the method is suitable for testing large-scale clinical samples, and has the characteristics of being rapid, high-throughput, high-sensitivity and high-specificity.

Description

technical field [0001] The present invention relates to the field of immunology. Specifically, the present invention relates to a monoclonal antibody against the Brucella lipopolysaccharide common antigen, a c-ELISA method based on the monoclonal antibody, a kit containing the monoclonal antibody and a diagnostic detection reagent. Background technique [0002] Brucellosis is a zoonotic infectious disease caused by Brucella bacteria. Causes miscarriage, infertility and arthritis among other symptoms. People infected with Brucella produce more serious symptoms, such as wave fever, unbearable joint and muscle pain, loss of working ability, and also affect fertility, and severe cases can cause death. It is prevalent in more than 160 countries and regions. The brucellosis epidemic in my country was well controlled from the late 1980s to the early 1990s. Since 1993, the brucellosis epidemic in my country has been increasing year by year. The world suffers huge economic losses ...
