FIG. 3.

Immunoblocking ability of mouse anti-EP antiserum. Western blot analysis of false positives F1 and F2 against crude EP with a standard blocking procedure or the application of different dilutions of mouse anti-EP Ab in the blocking procedure. The numbers and intensities of the bands decreased as the applied dilution of mouse anti-EP Ab increased, revealing the potential use of mouse anti-EP Ab to block the binding between EP and human anti-EP Ab specifically. NA, not applicable.
