Antibody levels and specificity of pEGFP-N1-Catsper1-injected male mice.

<p>(A) Serum IgG antibody response of immunized male mice by ELISA. M1-M6 represent 6 individual mice. The 0 week on horizontal axis represents the time point before the first immunization, and others represent the weeks after first immunization. P34 and Pp6 were used as coating antigen in the ELISA assay respectively. (B) The specificity of antibodies in serum of immunized mice. Scale bar = 20 μm.
