In conjunction with this capability it is important to have available highly sensitive and quantitative potency assays. The potential suitability of enzyme-linked immunoassay (ELISA) was evaluated using animal sera with neutralizing antibodies or neutralizing monoclonal antibodies for antigen detection in potency tests. The monoclonal antibodies developed, which bound D antigen but not C antigen, were neutralizing unless relatively weakly reactive. Those that bound C antigen only were non-neutralizing. Those that bound both C and D antigens were sometimes neutralizing. D-specific and D/C-specific neutralizing monoclonal antibodies against type-2 poliovirus protected mice on passive immunization against paralytic disease and death from the MEF strain virus. Potency measurements by ELISA using either D-specific neutralizing monoclonal antibodies or type-specific goat sera for antigen detection were sensitive and precise. Tests using C-specific monoclonal antibodies for antigen detection indicated that increased C antigen content may result in falsely elevated reactivities of animal sera with some vaccines.

The earlier fever activity appeared to correlate with endotoxin activity in individual vaccines while the later appeared to correlate with histamine-sensitizing factor (HSF) activity. The later peak fever activity was greatly reduced by heating the vaccine at 100 °C for 30 min while the first was little affected by such treatment.
