A Method for Coupling Protein Antigens to Erythrocytes


A serological technique, using formalinized red cells coupled to tuberculin PPD as antigen, has been assayed in a trial series of 124 tuberculous and 139 non-tuberculous patients. The stability of the antigen preparation, and the omission of an adsorption procedure for the removal of isoagglutinins facilitated the performance of the test. The results… (More)
