Monoclonal antibody and preparation method thereof

Abstract

The invention discloses a monoclonal antibody and a preparation method thereof. The monoclonal antibody comprises anti-PGAM, CoI alpha, Trx, PGAM 13, CoI alpha 12 and Trx 11. The preparation method comprises the following steps: immunizing mice by embedding PGAM, CoI alpha, Trx, PGAM 13, CoI alpha 2 and Trx 11 in spleens; fusing spleen cells of the mice with myeloma cells SP2/0 of the mice; and detecting the cells by indirect ELISA and culturing supernatant. 3, 2, 5, 3, 4 and 3 strains of monoclonal antibodies for resisting PGAM, CoI alpha, Trx, PGAM 13, CoI alpha 12 and Trx 11 are respectively obtained, and homotypes of the antibodies are IgM.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a monoclonal antibody and a preparation method thereof. Background technique [0002] The main function of antibodies is to combine with antigens (including foreign and self), so as to effectively remove foreign substances such as microorganisms and parasites invading the body, especially monoclonal antibodies, because of their high uniformity and specific antigen expression. Therefore, it is widely used in the fields of immunological analysis, radioimmunoimaging and immune-guided therapy. The development of monoclonal antibodies has gone through four stages, namely: murine monoclonal antibodies, chimeric monoclonal antibodies, humanized monoclonal antibodies and fully human monoclonal antibodies. Mouse-derived monoclonal antibody: mouse hybridoma monoclonal antibody mainly fuses B cells from immunized mice with myeloma cells, and then screens out mouse hybrid fusio...
