摘要

Hybridoma cell lines which produce monoclonal antibodies to Shiga toxin from Shigella dysenteriae 1 were prepared. The monoclonal antibodies were all of the immunoglobulin G1 isotype and differed in their ability to neutralize cytotoxicity and to bind to Shiga toxin in a solid-phase radioimmunoassay. When used for immunoblot analysis, these antibodies were able to identify specifically both nicked and unnicked Shiga toxin in crude lysates of S. dysenteriae.
