Comparison of conventional NT with eGFP-NT, HI and ELISA of 57 chicken serum samples. a Correlation of conventional NT and eGFP-NT. Neutralization titers (X-axis) are given as the log2 of the reciprocal serum dilution in which 100% CPE is inhibited. eGFP-NT titers (Y-axis) are given as the log2 of the maximal reciprocal serum dilution in which all wells show non-eGFP expression. b Correlation of conventional NT and HI. HI titers (Y-axis) are given as the log2 of the maximal reciprocal serum dilution in which hemagglutination is inhibited. c Correlation between NT titers (X-axis) and ELISA titers (Y-axis). ELISA is given as the S/P ratio
