Compositions and methods for diagnosing high-grade cervical disease in a patient sample are provided. The compositions include novel monoclonal antibodies, and variants and fragments thereof, that specifically bind to MCM6 or MCM7. Monoclonal antibodies having the binding characteristics of an MCM6 or MCM7 antibody of the invention are further provided. Hybridoma cell lines that produce an MCM6 or MCM7 monoclonal antibody of the invention are also disclosed herein. The compositions find use in practicing methods for diagnosing high-grade cervical disease comprising detecting overexpression of MCM6, MCM7, or both MCM6 and MCM7 in a cervical sample from a patient. Kits for practicing the methods of the invention are further provided. Polypeptides comprising the amino acid sequence for an MCM6 or an MCM7 epitope and methods of using these polypeptides in the production of antibodies are also encompassed by the present invention.

Monoclonal antibodies and methods for their use in the detection of cervical disease

Methods and compositions for identifying high-grade cervical disease in a patient sample are provided. The methods of the invention comprise detecting overexpression of at least one biomarker in a body sample, wherein the biomarker is selectively overexpressed in high-grade cervical disease. In particular claims, the body sample is a cervical smear or monolayer of cervical cells. The biomarkers of the invention include genes and proteins that are involved in cell cycle regulation, signal transduction, and DNA replication and transcription. In particular claims, the biomarker is an S-phase gene. In some aspects of the invention, overexpression of a biomarker of interest is detected at the protein level using biomarker-specific antibodies or at the nucleic acid level using nucleic acid hybridization techniques. Kits for practicing the methods of the invention are further provided.

Methods and compositions for the detection of cervical disease

The invention relates to methods of using spectroscopically detectable labeled receptor molecules to determine the presence or absence of a target compound in a sample. In one embodiment, spectroscopically detectable labeled nucleic acid ligands are used to determine the presence or absence of biological targets of interest in biological samples.
