FIG. 4.
Evaluation of the reactivity of antigens to rabbit anti-S2 polyclonal antibodies and EIAV-infected horse serum in standard ELISA and NN-ELISA. Shown are HS2G reactivities to rabbit anti-S2 polyclonal antibodies (1:200 dilution) and to EIAV-infected horse immune serum (1:25 dilution) in the standard ELISA (A) or the affinity NN-ELISA (B) format.
