| Research Abstract |
Immune agglutinin or precipitin loses its reactivity with the corresponding antigen by heating or some chemicals. A.Se group seliva or M group blood stain was sensitized with human IgM anti-A or rabbit IgG anti-M serum,respectively. After being washed with saline, the stains were heated or treated with formalin or 2-mercaptoethanol(2-ME) or various concentrations. The immunoreactivity of the antibodies in the state of immunecomplex was examined by the mixed agglutination or elution test, indicating IgM and IgG antibodies in the state of immunecomplex were proof against heating up to 150C for 10 min and against formalin and 2-ME of high concentrations. It is considered that IgM and IgG acguire a new property of heat and chemical stability by formation of immunecomplex although they are substantially heat and chemical fabile
