  • Publication number: 20240084287
    Abstract: The present invention relates to the analysis of complex single cell sequencing libraries. Disclosed are methods for enrichment of library members based on the presence of cell-of origin barcodes to identify and concentrate DNA that is relevant to interesting cells or components that would be expensive or difficult to study otherwise. Also, disclosed are methods of capturing cDNA library molecules by use of CRISPR systems, hybridization or PCR. The present invention allows for identifying the properties of rare cells in single cell RNA-seq data and accurately profile them through clustering approaches. Further information on transcript abundances from subpopulations of single cells can be analyzed at a lower sequencing effort. The methods also allow for linking TCR alpha and beta chains at the single cell level.

  • Publication number: 20230287396
    Abstract: This disclosure relates to compositions and methods for amplifying and identifying a target nucleic acid of interest from a population of non-target nucleic acids. In particular, this disclosure provides compositions and methods for identifying a target sequence from a single known adjacent sequence. This disclosure provides compositions and methods useful for identifying rare sequence variants, gene fusions, and for enriching and identifying nucleic acid whose target region of interest and its barcode for single-cell tracing are located on distant portions of a molecule.

  • Publication number: 20220267764
    Abstract: Disclosed herein are methods for counting nucleic acid molecules (e.g., RNA molecules) of a sample by randomly truncating the nucleic acid molecules at a truncation base position within the nucleic acid molecules to produce truncated nucleic acid molecules, amplifying and sequencing the truncated nucleic acid molecules to produce sequencing reads, aligning the sequencing reads to a reference sequence to produce aligned sequencing reads, and identifying a number of nucleic acid molecules using truncation locations of aligned sequencing reads. Also disclosed herein are methods for constructing sequencing libraries that preserve truncation positions of the nucleic acid molecules. Also disclosed herein are methods for depleting or enriching a sample for one or more target sequences, using sets of blocking oligonucleotides corresponding to the one or more target sequences.
