title: Studies of thyroglobulin autoantibody synthesis using a micro-ELISA assay.
abstract: Thyroglobulin autoantibody synthesis by Hashimoto lymphocyte cultures has been studied using an ELISA, a plaque assay and tanned red cell haemagglutination. The ELISA system was found to be the most suitable and using this method IgG-class thyroglobulin antibody synthesis was detectable in cultures of mitogen-stimulated lymphocytes from all 10 Hashimoto patients studied, but not in cultures of lymphocytes from 4 normal donors. The ELISA was also sufficiently sensitive to detect thyroglobulin antibody synthesis in mitogen-free lymphocyte cultures from 4 out of the 10 Hashimoto patients and consequently it should be possible to use this system to study the effect of various pathophysiological factors on autoantibody synthesis which would otherwise be masked by mitogenic stimulation.
