title: Further studies on the adjuvant effect of silica on IgE antibody production in mice.
abstract: The effects of amorphous silica (Aerosil) and of aluminium hydroxide on anti-DNP IgE antibody production were studied in Swiss mice preimmunized with Ascaris protein and then challenged 7 days later with DNP-ASC. Aerosil exerted an adjuvant effect especially when it was injected together with the DNP-ASC conjugate. Al(OH)3 had a weaker adjuvant effect than that produced by Aerosil and then only when it was injected with the DNP-ASC conjugate. Al(OH)3 given with Ascaris extract 7 days before complete antigen had an inhibitory effect on the anti-DNP IgE antibody production.
