  • Patent number: 11598942
    Abstract: A multi-channel line microscope for single molecule Fluorescence In Situ Hybridization (FISH) imaging of a sample. A microscope stage moves a sample across two or more reflected excitation lines positioned relative to each other so that each excitation line excites a spatially distinct horizontal line in the image plane of the sample. A sample is imaged by moving the microscope stage across two or more reflected excitation lines positioned relative to each other so that each excitation line excites a spatially distinct horizontal line in the image plane of the sample. The apparatus and methods of use are suitable for a broad range of applications.

  • Publication number: 20220396833
    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.

  • Publication number: 20210017587
    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 specific molecular targets through sequential hybridization experiments. A pseudo-color based barcoding scheme is developed to overcome limitations in the previous generation of the technology such as lack of visual signals that can be associated with the probes or small internal within cell when carrying out in situ experiments. The current method can be applied to both in vitro and in situ analysis. According to the method, each barcoding round comprises multiple serial hybridizations where a small number of colored signals (that are associated with probes) are used in each hybridization experiment within a serial hybridization round. Images from each serial hybridization experiment within the same serial hybridization round are combined to form a composite image for each barcoding round.
