Approach to molecular diagnosis of human papillomavirus-related diseases
The present invention relates to an accurate, sensitive, and efficient sequential or concurrently sequential method for molecular diagnosis of human papillomavirus (HPV)-based disease, where the method improves the accuracy and reliability of diagnostic and prognostic assessments of HPV-based disease. The method of the invention comprises a primary screen of a sample for HPV nucleic acids, followed by a secondary screen for molecular markers, such as proliferation and cell cycle control group protein markers. The sequential or concurrently sequential method significantly reduces the number of false positive results.
1. A kit for detecting high risk HPV nucleic acids and subsequently detecting protein marker expression in a sample, comprising reagents for detecting molecular characteristics in a biological sample, wherein the reagents consist essentially of at least two probes capable of detecting high risk HPV nucleic acids in a sample, at least two primary antibodies that are specific to two different protein markers, wherein the protein markers are selected from the group consisting of: PCNA and Ki-67, PCNA and p16, and PCNA, Ki-67 and p16.
2. The kit according to claim 1 , wherein the at least two probes are selected from the group consisting of a DNA probe and an RNA probe.
3. The kit of claim 1 , wherein the kit further comprises instructions for detecting the HPV nucleic acids by hybridization under low stringency conditions.
4. The kit of claim 1 , wherein the protein markers are PCNA and Ki-67.
5. The kit of claim 1 , wherein the protein markers are PCNA and p16.
6. The kit of claim 1 , wherein the protein markers are PCNA, Ki-67 and p16.
