Specific Suppression of Anti-Hapten Reaginic Antibody Titers with Hapten-Coated Liposomes

Reaginic antibodies to DNP and ovalbumin (OA) were induced in B6D2F1 mice by a single i.p. injection of 1 microgram of DNP3-OA suspended with 1 mg of A1(OH)3 in 0.5 ml of saline. The anti-DNP reaginic antibody titers were markedly depressed by treatment of mice with DNP-coated liposomes. This treatment, however, did not affect the level of antibody formation to OA.
