Abstract
Monoclonal (MAbs) and polyclonal antibodies were produced against the major capsid protein of detergent-disrupted, purified bovine papillomavirus type 1 (BPV-1). The precise locations of the corresponding epitopes were identified by the reactivity of MAbs and selected polyclonal antibodies with synthetic, overlapping, hexameric peptides corresponding with 95% of the BPV-1 major capsid protein. The topography of these epitopes was determined by reactivity of antibodies with intact (conformational and nonconformational surface epitopes) and disrupted (external or internal nonconformational epitopes) BPV-1 virions. The distribution of epitopes in various papillomaviruses of 13 different species was determined by reactivity of the MAbs and polyclonal sera with productively infected, formalin-fixed papillomas, fibropapillomas, and fibromas. Epitope scanning, using MAbs and polyclonal antisera, resulted in the precise location of BPV-1 hexameric epitopes that could be correlated with their topography on the capsid and distribution in papillomatous lesions of various species.
