ELISA was used to detect anti-p32 IgG in each group. Cut off calculation: cut off = average value of negative control + 0.15. When the negative control value was ≤ 0.05, it was calculated as 0.05. Positive judgment: samples with OD value ≥ cut off were judged as positive. Negative determination: samples with OD value < cut off were judged as negative. SFV-p32 RP-immunized mice are numbered 1–5, which are consistent with the numbers assigned to mice detected by pre-immune serum, the second immunization and the third immunization in the FIGURE.
