The methods comprise contacting a nucleic acid sample with a multimeric barcoding reagent comprising barcode regions linked together and appending barcode sequences to nucleic acid sequences of a target nucleic acid molecule. Methods are also provided that additionally use in-vitro transposition, coupling sequences and/or primer-extension to append barcode sequences to nucleic acid sequences of a target nucleic acid molecule.

Abstract: Multimeric barcoding reagents for labelling a target nucleic acid comprise: first and second barcode molecules linked together, wherein each of the barcode molecules comprises a nucleic acid sequence comprising a barcode region; and first and second barcoded oligonucleotides. The multimeric barcoding reagents enable spatial sequencing. A single multimeric barcoding reagent can be used to label sub-sequences of an intact nucleic acid molecule or co-localised fragments of a nucleic acid molecule. The labelled sub-sequences can be sequenced and the sequencing data processed to determine the sequence of sub-sequences from a single intact nucleic acid molecule or from co-localised fragments of a nucleic acid molecule. Corresponding libraries, kits, methods and uses are provided.

Abstract: Reagents and methods for the analysis of cell free biomolecules (e.g. cell free nucleic acid molecules and cell free polypeptides) of microparticles (e.g. cell-free microparticles originating from blood, or cell-free microparticles originating from an embryo generated by in vitro fertilisation) are provided. Also provided are reagents and methods for the analysis of biomolecules (e.g. nucleic acid molecules and polypeptides) of cells (e.g. cells originating from blood, or cells originating from an embryo generated by in vitro fertilisation). The methods comprise analysing a sample that comprises a microparticle (or cell) or a sample derived from a microparticle (or cell). The methods include methods of measuring at least two linked signals, each signal corresponding to the presence, absence and/or level of a biomolecule of a microparticle (or cell). The methods also include methods of determining the presence, absence and/or level of a biomolecule of a microparticle (or cell) using a barcoded affinity probe.

Abstract: Reagents and methods for the analysis of nucleic acids (e.g. genomic DNA) of circulating microparticles (i.e. microparticles originating from blood) are provided. The methods comprise linking at least two fragments of a target nucleic acid of a circulating microparticle to produce a set of at least two linked fragments of the target nucleic acid. In the methods, fragments of a target nucleic acid may be linked by techniques such as barcoding, partitioning, ligation and/or separate sequencing. The sequencing of a set of linked fragments provides a set of informatically linked sequence reads corresponding to the sequences of fragments from a single microparticle.
