Abstract
This protocol describes the production of human papillomavirus (HPV)-derived quasiviruses. Quasiviruses are infectious particles that are produced in 293TT packaging cells and contain a complete viral genome. We describe methods for infection of primary human keratinocytes with HPV quasiviruses, as well as assays to measure early viral DNA replication and transcription. Published 2020. U.S. Government.
