D-antigen ELISA selectivity. IPOL (panel A) and VeroPol (panel B) were treated by heating at 56 °C for 1 h to convert D-antigen to H-antigen, mixed with untreated vaccine at different ratios, and tested by ELISA. Plots depict the theoretical and the measured D-antigen content of IPV 1, IPV 2, and IPV 3 demonstrate D-antigen selectivity for each vaccine studied.
