Figure 3From: Identification of a conserved linear B-cell epitope in the M protein of porcine epidemic diarrhea virusPrecise localization of the McAb 4D4-defined epitope. The reactivity of McAb 4D4 with different truncated M proteins was determined by ELISA (A) and WB (B and C). The names of the peptides are the same as in Table 1. “His” and “GST”, representing the 6×His tag and the GST tag, were used as negative controls, and the GST-tM protein was used as the positive control.
