title: Induction of delayed reaction to dinitrophenylated lymphocytes in guinea pigs with contact sensitivity to DNCB.
abstract: The incidence of dinitrophenylated cells in guinea pig lymphocytes incubated with 0-30 mM concentrations of DNBSO3Na in phosphate-buffered saline was examined by an immunofluorescence method using fluorescence-labelled anti-DNP antibody. Under our experimental conditions, the incidence was roughly proportional to the concentration used. Using DNP-lymphocytes as an antigen for skin testing, a marked delayed reaction was induced in guinea pigs sensitized by painting with DNCB and intradermal injection of Freund's complete adjuvant. The significance of these findings is discussed.
