  • Publication number: 20230227889
    Abstract: Methods of preparing a plurality of sample-barcoded anchor-domain-flanked gene specific deoxyribonucleic acid (DNA) fragments from a template nucleic acid, e.g., ribonucleic acid (RNA), sample are provided. Aspects of the methods include employing a set of gene specific primer pairs, wherein each pair of gene specific primers is made up of a forward primer and a reverse primer, at least one of which includes a sample barcode domain. The methods find use in a variety of different applications, including high-throughput sequencing, e.g., expression profiling, applications, including of small biological samples, e.g., single-cells.

  • Publication number: 20220145285
    Abstract: Compartment-free single cell genetic analysis methods are provided. Aspects of the methods include: (a) combining a cellular sample with a plurality of distinct barcoded beads comprising barcoded reverse primers under conditions sufficient to produce a liquid composition comprising a plurality of separated cell/barcoded bead complexes; (b) hybridizing template binding domains of barcoded reverse primers to template nucleic acids of the cells to produce primed template nucleic acids; and (c) subjecting the primed template nucleic acids to primer extension reaction conditions sufficient to produce barcoded nucleic acids, e.g., for subsequent amplification and analysis, such as by Next Generation Sequencing (NGS) protocols. Also provided are compositions that find use in practicing embodiments of the methods.

  • Publication number: 20210301329
    Abstract: Single cell genetic analysis methods are provided. Aspects of the methods include: (a) producing a plurality of partitioned cell/barcoded bead complexes from a cellular sample and a plurality of distinct barcoded beads that include a plurality of barcoded reverse gene-specific primers; (b) hybridizing gene-specific template binding domains of the barcoded reverse gene-specific primers to template nucleic acids of the cells to produce primed template nucleic acids; and (c) subjecting the primed template nucleic acids to primer extension reaction conditions sufficient to produce barcoded nucleic acids, e.g., for subsequent amplification and analysis, such as by Next Generation Sequencing (NGS) protocols.
