Studies on the tuberculin reaction part 2. a study on tuberculin protein, nuclear protein, and polysaccharide fraction in the tuberculin reaction and erythrocyte coagulation reactionUsing the protein, nuclear protein and polysaccharide fractions obtained from old tuberculin by salt analysis or by paperelectrophoresis the author performed the tuberculin reaction and erythrocyte coagulation reaction, and obtained the following results:...
Presence of a substance in the third international standard of old tuberculin that interacts negatively with the biological potency of the preparationIn the course of experiments designed as part of a biological assay of the Third International Standard of Old Tuberculin (OT) it was noticed that this preparation at the usual concentrations failed to elicit the expected concentration-response in persons on whom the von Pirquet was...
Mycobacterial components responsible for the induction of a chronic immunological inflammatory response in rabbit lungs... We found that emulsions containing old tuberculin and even old tuberculin alone in an emulsion could induce a pulmonary inflammatory reaction comparable in intensity to that produced with killed BCG....
