IFA analysis of positive/negative reference serum and monoclonal antibody No.2. Positive reference serum (B) and monoclonal antibody No.2 (F) recognized the nucleocapsid protein in PDCoV-infected LLC-PK1 cells, while negative reference serum (D) did not react. Uninfected LLC-PK1 cells (A, C and E) were used as a negative control. Serum +: positive reference serum; serum -:negative reference serum. The bars in A, B, C and D represent 100 μm, and the bars in E and F represent 50 μm
