  • Publication number: 20260015654
    Abstract: The present invention, among other things, provides technologies for detecting and/or quantifying nucleic acids in cells, tissues, organs, or organisms. Pre-designed barcodes are associated with specific molecular targets through sequential hybridization experiments. A pseudo-color based barcoding scheme is described that overcomes the limitations in the previous generation of the technology. The current method can be applied to both in vitro and in situ analysis.

  • Patent number: 12516373
    Abstract: Disclosed herein include systems, methods, compositions, and kits for in situ readout of barcodes, such as DNA barcodes. Barcode constructs containing a promoter (e.g., a phage promoter) that is inactive in live cells can be integrated in the genomes of cells. Cells can be fixed, and phage RNA polymerase can be used for transcription of the barcode to RNA transcripts. The RNA transcripts can be detected using, for example, fluorescent imaging and used to determine barcode sequences.
