From: Immunization with Pneumocystis carinii A121–85 antigen activates immune function against P. carinii
Recombinant A121–85 immunization increased the serum titer of IgG. (A) Comparison of serum titer of IgG between three groups of mice 42 days after immunization. (Group A: immunization with recombinant A121–85-adjuvant; Group B: immunization with PBS-adjuvant; Group C: immunization with PBS. *: P < 0.05; **: P < 0.01; ***: P < 0.001); (B) Immunized with A121–85 gradually increased IgG titer with the increase of immunization times (The red plot presents effective titer)
