On the adjuvant effect of aluminum hydroxide for mice

Linear relationships were found between the dose of A1(OH)3 adjuvant and the titer of anti-OVA antibodies formed by BDF1 mice. Mice immunized with OVA, DNP-KLH and then boosted with DNP-OVA formed anti-DNP antibodies only when A1(OH)3 was added to the injection of DNP-KLH; addition of A1(OH)3 to the priming injection of OVA decreased, rather than increased antibody formation.
