In some aspects, the present disclosure relates to methods for reducing the crowding of signals, for example optical crowding, that can occur when nucleic acids are detected in a sample in multiplex, which can make it difficult to resolve individual signals and can lead to a reduced dynamic range. In some aspects, the present disclosure relates to methods for reducing signal crowding in the detection of multiple target nucleic acid sequences in a sample, e.g., using hybridization probes, wherein signal crowding from said hybridization probes is reduced. The methods herein have particular applicability in the detection of barcode sequences by sequencing-by-hybridization (SBH) methods, including those relying on combinatorial labelling schemes and decoding of the barcodes by sequential cycles of decoding using hybridization probes. Also provided are kits comprising probes for use in such methods.

The present invention relates to methods of diagnosing and/or treating head and neck squamous cell carcinoma (HNSCC) in a subject. The present invention further relates to methods of diagnosing and/or treating head and neck squamous cell carcinoma (HNSCC) in a subject, wherein the subject has been diagnosed as being positive for human papillomavirus (HPV

The present disclosure relates in some aspects to methods for preparing biological samples for in situ analysis of one or more analytes, wherein the biological sample has been previously affixed to a substrate, which is not compatible with in situ analysis, for example, due to the absence of positional markers and/or fiducial markers and/or a region suitable for in situ signal detection on the substrate.

The present application provides methods, compositions, and kits for analyzing a biological sample embedded in a three-dimensional polymerized matrix using a primer-exchange reaction (PER). In some embodiments, the methods comprise contacting the sample with a nucleic acid molecule that directly or indirectly binds to an analyte in the sample and immobilizing the nucleic acid molecule in the matrix, wherein the nucleic acid molecule comprises a free 3′ priming region for initiation of PER. In some embodiments, the methods enable sensitive detection of the identity and relative position of analytes in the sample.
