摘要: A cytochemical bioassay for thyroid stimulators which utilised 12 micrometer sections of guinea pig as the target tissue was validated and applied to measurement stimulating antibodies (T.S.Ab.) in human plasma. T.S.H. T.S.Ab. could be distinguished assay by times at they produced maximal responses; 90 seconds 180 Homogeneity responses stimulation relatively uniform throughout enabling simultaneous several plasma samples per pig. Sensitivity 1.5 x 10(-9) microU/l MRC L.A.T.S.-B. Antiserum H-T.S.H. no significant change T.S.Ab.-like activity when added from a thyrotoxic patient. Both anti-IgG aliquots homogenate patient diminished concentration dependent manner. present titres 1/100 1/100,00 13 hyperthyroid patients tested date.
