Figure 2From: Induction of neutralizing antibodies specific for the envelope proteins of the koala retrovirus by immunization with recombinant proteins or with DNANeutralizing capacity of the induced antisera. Neutralization of KoRV by rat sera after immunization with recombinant rgp70/p52 protein (A), recombinant zp15E protein (B) and both proteins together (C). The titers of neutralizing antibodies in the sera from goats immunized with rgp70/p52, and rp15E are shown in (D). A serum obtained by immunization with the recombinant rp27Gag (which is not neutralizing) was included for comparison. The dashed line indicates 50% neutralization.Back to article page
