Cross-reactivity of antisera to CCHFV and NSDV NPs. ELISA plates were coated with 10 µg/ml of purified CCHFV NP, NSDV NP, or the mock antigen. Serial dilutions (1:100, 1:1,000, 1:10,000, and 1:100,000) of mouse antiserum to CCHFV, to NSDV NP, and naïve mouse serum were used as primary antibodies and incubated for 2 h at 4 °C. Peroxidase conjugate goat anti-mouse IgG (H + L) was used for detection of bound antibodies. To offset the nonspecific antibody reaction, the OD value of the mock antigen was subtracted for each dilution.
