The present disclosure in some aspects relates to methods and compositions for accurately detecting and quantifying multiple analytes present in a biological sample. In some aspects, the methods and compositions provided herein address one or more issues associated with the stability and/or size of nucleic acid structures such as rolling circle amplification products in the biological sample.

Stabilization and/or compaction of nucleic acid structures

Stabilization and/or compaction of nucleic acid molecules

In some aspects disclosed herein are methods and compositions for detecting a target nucleic acid molecule, said method comprising performing a linear oligo hybridization chain reaction (LO-HCR) to generate a polymeric product, and detecting the polymeric product, thereby detecting the target nucleic acid molecule.

Methods of detecting an analyte

The present application provides compositions, systems, and methods for encoding and decoding nucleic acid molecules.

Sequential decoding of nucleic acids

The present disclosure relates in some aspects to methods and compositions for analysis of a target nucleic acid, such as in situ detection of a region of interest in a polynucleotide in a tissue sample. In some embodiments, provided herein are templated ligation probes (e.g., RNA-templated ligation probes) and selector probes for generation of a circularized ligated probe comprising an insertion sequence of a selector probe, wherein the circularized ligated probe is amplified in a rolling circle amplification reaction to generate a product that is detected in the sample.

Circularizable probes for in situ analysis

The present application provides methods for detecting a nucleic acid molecule involving the use of a signal code sequence which corresponds to said nucleic acid molecule and a plurality of labelled detection probes which yield signals which make up the signal code sequence. In particular, the invention provides a sequential barcoding and decoding scheme which utilises a sequencing-by-hybridisation (SBH) strategy to sequence and decode a nucleotide barcode sequence, and to differentiate the nucleotide barcode sequence from other nucleotide barcode sequences. In an extension of the method, the application also provides a new coding scheme for providing a target nucleic acid with a detectable 'colour' (or similar signal)-based code.
