Six hybridomas that secrete monoclonal antibody to Toxoplasma gondii have been developed. Four of these secrete antibody of the IgG1 subclass, one secretes antibody of the IgG2a subclass and the remaining hybridoma secretes antibody of IgG3 subclass. One IgG1 subclass antibody reacts only in the indirect haemagglutination antibody test (IHAT), four (3 IgG1 and 1 IgG2a) react only in the indirect immunofluorescence antibody test (IFAT), and the IgG3 antibody reacts in both the IHAT and IFAT.
