  • Publication number: 20230348899
    Abstract: The present invention relates to methods of detecting region(s) of interest in a gene comprising a polyA tail. The region(s) of interest can include gene(s), region(s), mutation(s), deletion(s), insertion(s), indel(s), and/or translocation(s). The region(s) can be greater than or less than 1 kilobases from the polyA tail. Methods can include forming a library of single cell transcripts comprising the region(s) in close proximity to a cell barcode and a unique molecular identifier (UMI). Methods for distinguishing cells by genotype can include amplifying the transcripts using PCR methods and detecting the cell barcode and UMI using single cell sequencing methods. Transcripts can be enriched using tagged region-specific PCR primers. Cell barcodes can be brought into close proximity to the region(s) by circularizing the transcripts. Sequencing of the transcripts can include using primer binding sites added during PCR amplification and library indexes for multiplexed sequencing.

  • Publication number: 20200248175
    Abstract: The present invention relates to methods of deriving genetic information from RNA-seq libraries, that can enable an overlay of genetic information (such as cancer driver mutations) onto single-cell transcriptomes and permitting efficient identification, localization, and quantification of certain cells of interest within a population as well as provide low-cost selection and sequencing of any portion of a transcript, including at the 5? end.

  • Publication number: 20130304096
    Abstract: An embodiment in accordance with the present invention provides a device and method for suturing the fascia or other tissue in a patient. The device includes a first arm and a second arm pivotally coupled to one another and housing a spring-based lever system that is configured to frictionally hold a portion of a needle within each of the first and second arms. A switch allows the spring-based lever system to be used to pass the needle between the first and second arms. When the switch is in a first position, the needle is frictionally held by the spring-based lever system within the first arm and released within the second arm. Likewise, when the switch is in a second position, the needle is frictionally held by the spring-based lever system within the second arm and released within the first arm.
