The distribution of 2,4-dinitrophenyl groups in guinea pigs following feeding of 2,4-dinitrochlorobenzene.
An immunofluorescent technique using anti-DNP antibody was employed to investigate the distribution of 2,4-dinitrophenyl (DNP) groups in various tissues following the feeding of 125 mg/kg 2,4-dinitrochlorobenzene (DNCB)-ethanol to guinea pigs that had been starved for 1 day. DNP groups were detected in the areas corresponding to the cytoplasm and the cell membrane of the epithelium in the upper gastrointestinal tract as well as on the cells of mesenteric lymph nodes, Payer's patches, the spleen, and peripheral blood. These results are discussed in relation to the mechanism of tolerance induction produced by the feeding of haptens.
