High throughput cell-based hpv immunoassays for diagnosis and screening of hpv-associated cancers

Abstract

Methods for quantifying an HPV protein expression in a clinical sample are disclosed. The quantifying methods include the process for obtaining the clinical sample. Such a clinical sample is consisted of a population of cells that are susceptible to infection by an HPV. The quantifying methods also include the process for depositing the clinical sample into a container. The clinical sample is contacted with the first antibody that specifically binds to an HPV protein which is expressed by an HPV-infected cell under a condition that promotes specific binding of the first antibody to the HPV protein expressed by the population of cells. The methods further include the process for quantifying the specific binding of the first antibody and thereby quantifying the HPV protein expression in the clinical sample. The assay provides an objective test to identify patients with high-grade precursor from cytology samples before biopsy.
