Presented herein are methods and compositions for enhancing specific enrichment of target sequences in a nucleic acid library. Off-target hybridization probes may be used to reduce binding and/or capture of off-target regions of a nucleic acid library in a targeted sequencing workflow. The off-target hybridization probes may be specific for locations known to generate off-target sequencing reads for a particular set of hybridization probes.

Systems and methods for conducting designated reactions utilizing a base instrument and a removable cartridge. The removable cartridge includes a fluidic network that receives and fluidically directs a biological sample to conduct the designated reactions. The removable cartridge also includes a flow-control valve that is operably coupled to the fluidic network and is movable relative to the fluidic network to control flow of the biological sample therethrough. The removable cartridge is configured to separably engage a base instrument. The base instrument includes a valve actuator that engages the flow-control valve of the removable cartridge. A detection assembly held by at least one of the removable cartridge or the base instrument may be used to detect the designated reactions.

Haplotype-resolved genome sequencing enables the accurate interpretation of medically relevant genetic variation, deep inferences regarding population history and non-invasive prediction of fetal genomes. We describe an approach for genome-wide haplotyping based on contiguity-preserving transposition (CPT-seq) and combinatorial indexing. Tn5 transposition is used to modify DNA with adaptor and index sequences while preserving contiguity. After DNA dilution and compartmentalization, the transposase is removed, resolving the DNA into individually indexed libraries. The libraries in each compartment, enriched for neighboring genomic elements, are further indexed via PCR. Combinatorial 96-plex indexing at both the transposition and PCR stage enables the construction of phased synthetic reads from each of the nearly 10,000 'virtual compartments'. We demonstrate the feasibility of this method by assembling >95% of the heterozygous variants in a human genome into long, accurate haplotype blocks (N50 = 1.4–2.3 Mb). The rapid, scalable and cost-effective workflow could enable haplotype resolution to become routine in human genome sequencing. © 2014 Nature Publishing Group, a division of Macmillan Publishers Limited.
