Fig. 2From: Peptide enzyme‐linked immunosorbent assay (pELISA) as a possible alternative to the neutralization test for evaluating the immune response to IBV vaccineThe correlation between the ELISA titer and neutralization titer for serum antibodies against IBV. Comparison of the titers measured by pELISA and a neutralization assay for chicken sera against CK/CH/2010/JT1 (a), CK/CH/2014/FJ14 (b). M41 (c), and the H52 attenuated vaccine (d). The ELISA titer means the maximum dilution of the serum sample with OD value greater than the pELISA’s cut-off. There were five serum samples evaluated at each time point, and each serum sample was independently tested three timesBack to article page
