Detection of Human Papillomavirus Type 31-Neutralizing Antibodies from Naturally Infected Patients by an Assay Based on Intracellular Assembly of Luciferase-Expressing Pseudovirions

摘要

The aim of this study was to develop a highly sensitive human papillomavirus type 31 (HPV31) neutralization assay based on the production of pseudovirions carrying luciferase. Neutralizing antibodies against HPV31 were investigated in a set of HPV31 monoclonal antibodies and in women with evidence of HPV31 infection. Neutralizing antibodies were detected in 78% of subjects with a positive enzyme-linked immunosorbent assay.
