RNASCOPE® HPV ASSAY FOR DETERMINING HPV STATUS IN HEAD AND NECK CANCERS AND CERVICAL LESIONS
The present invention provides a method and a kit for determining whether a head and neck cancer is HPV-related. In one embodiment, an RNAscope® HPV assay was designed to detect the presence of E6/E7 mRNA of certain high-risk HPV subtypes related to head and neck cancer. The present invention also provides a method and a kit for determining whether a cervical lesion is a benign lesion or a cervical intraepithethial neoplasm lesion. In one embodiment, an RNAscope® HPV assay was designed to detect the presence of E6/E7 mRNA of certain high-risk HPV subtypes related to cervical cancer. The present invention further provides a method for determining the progression of cervical intraepithethial neoplasm based on the spatial pattern and levels of the E6/E7 mRNA of certain high-risk HPV subtypes. The present invention also provides a method for determining the risk of developing cervical cancer in a human diagnosed with cervical intraepithethial neoplasm based on presence and absence of the certain subgroups of high-risk HPV subtypes.

AN ULTRA SENSITIVE METHOD FOR IN SITU DETECTION OF NUCLEIC ACIDS
Disclosed is a method for in situ detection of one or more target nucleic acids based on a combination of RNAscope® method and a general ISH signal amplification method. This new method produces high signal intensity and while keeps low background noise of signal amplification. The result can be consistently reproduced and the method can be easily adopted for routine clinic diagnostic use. Further, the invention relates to a kit, comprising the components of RNAscope® assay and a general ISH signal amplification assay, for sensitive detection of one or more target nucleic acids.
