The present study was undertaken to compare the effects of two adjuvants, SGP (a starch-acrylamide polymer) and Quil A (purified saponin), with that of aluminum hydroxide (Al(OH)3) on murine primary antibody responses to T-independent (TI) and T-dependent (TD) antigens. All three adjuvants augmented the responses to the TD antigens, dinitrophenyl-keyhole limpet hemocyanin (DNP-KLH), and sheep erythrocytes (SRBC). SGP was the most potent adjuvant and increased the primary IgG response to DNP-KLH as much as 90-fold. Quil A and Al(OH)3 had comparable effects on the primary response to DNP-KLH, but Quil A was less effective than Al(OH)3 for augmenting the primary response to SRBC. Quil A and SGP both augmented the primary IgM and IgG responses to trinitrophenyl-lipopolysaccharide (TNP-LPS), TNP-Brucella (TI-1 antigens), and TNP-Ficoll (TI-2 antigens). Al(OH)3, like most commonly used adjuvants, had little or no effect on responses to TI antigens. The kinetics of the response to TNP-Ficoll was altered by SGP, since peak responses were maintained for at least 7 days, while the response to TNP-Ficoll alone peaked on Day 4 and had declined considerably by Day 7. Both SGP and Quil A could augment responses to both optimal and suboptimal doses of antigen. The adjuvant activity of SGP was diminished, but still effective, when smaller amounts of SGP were used with the immunizing antigen, and all three adjuvants were able to augment primary responses when given in separate injections from the antigen. These results demonstrate that SGP is a very effective adjuvant, and show that both Quil A and SGP have a unique ability to increase antibody responses to TI antigens, suggesting that their effects may be mediated at least partially through B cells.
