  • Sandwich immunoassay kits for detecting ciguatoxin CTX3C
    Patent number: 7399470
    Abstract: A sandwich immunoassay kit for detecting ciguatoxins based on a combination of two anti-ciguatoxin CTX3C monoclonal antibodies produced by hybridomas, 3D11 (deposited at IPOD, AIST under accession number FMRM PB-8293) and 10C9 (FMRM PB-8292). In particular, one of the antibodies is labeled and each of them binds specifically to a different site of ciguatoxin CTX3C.
    Type: Grant

    Date of Patent: July 15, 2008
    Assignee: Japan Science and Technology Agency

  • Anti-ciguatoxin monoclonal antibody
    Publication number: 20040059096
    Abstract: The present invention offers the monoclonal antibodies that have a high specificity to ciguatoxins, which are the causative poisons of the ciguatera poisoning. The monoclonal antibodies were produced using synthetic hapten conjugates as artificial antigens, which were prepared by the conjugation of a synthesized hapten consisting of the IJKLM-ring fragment of ciguatoxins with proteins such as KLH, BSA, etc. The monoclonal antibodies show a specific reactivity to ciguatoxins, but little or almost no reactivity to other marine polyether toxins such as the okadaic acid, etc.
