Antigen-specific IgG responses in different immunised mice after the final immunisation. BALB/c mice were immunised with rBAG1 (A), rSRS4 (B), or rSRS9 (C) in combination with Freund’s adjuvant (black) or mindin adjuvant (red) or as proteins alone (blue). The IgG response was detected on week 9 (2 weeks after final immunisation). IgG levels are presented as optical density (OD) values at 405 nm with sera diluted from 1:1000 to 1:128,000. The statistical differences between the Freunds’ and the Mindin groups were significant in groups immunised with rBAG1 and rSRS9 (A and C), but not in the groups immunised with rSRS4 (C).
