Immune responses in PoMSP-8-immunized mice. a IgG levels in PoMSP-8-immunized mice. IgG was detected at day 7 post-immunization, and the levels increased throughout the whole immunization period. b Data are presented as the geometric mean OD obtained at different concentrations, expressed as the reciprocal of the serum dilution obtained from mice immunized with PocMSP-8 or PowMSP-8 (dilutions from 1:10,000 to 1:5,120,000). Numbers on the X-axis indicate the dilutions tested. Antigen specificity was confirmed using pre-immune serum samples as a control
