Monoclonal antibody-mediated neutralization of infectious human papillomavirus type 11.

Monoclonal antibodies recognizing human papillomavirus type 11 (HPV-11) were prepared from BALB/c mice immunized with intact HPV-11 virions obtained from morphologically transformed human foreskin xenografts grown subrenally in athymic mice. Four of five monoclonal antibodies that were reactive by enzyme-linked immunosorbent assay only to intact virions neutralized HPV-11 infectivity in the athymic mouse xenograft system.
