  • Patent number: 11512344
    Abstract: Provided herein are high-throughput, high-quality methods of consecutive in situ hybridization for analysis of the genome and/or transcriptome in an individual cell with single-molecule sensitivity. In particular, provided herein are methods comprising visualizing individual genomic loci or transcripts as single detectable signals (e.g., fluorescent spots) which remain in place during consecutive hybridization. In each cycle of consecutive hybridization, detectably labeled probes hybridize to the probe used in the previous cycle, and also introduce the binding sites for the probe of the following cycle. Through consecutive cycles of probe hybridization, imaging, and signal removal, different genomic loci or RNA species can be identified by unique detectable signal profiles (e.g., fluorescent spots with unique color sequences). The number of varied color sequences increases exponentially with the number of hybridization cycles, which enables the genome or transcriptome-wide analysis.

  • Publication number: 20220358607
    Abstract: A data linking system is described herein that links data records corresponding to a particular real estate property even if there are inconsistencies in the data records, the physical presence of the real estate property has changed over time, and/or the data records use different terminology. In some cases the data records are matched using a trained machine learning model. The data linking system can optionally generate a visualization of the data record linkage via interactive user interfaces. By linking data records despite the issues described above, the data linking system reduces the number of navigational steps a user performs to obtain data associated with a property and/or reduces data processing times. The disclosed system may be used to generate and maintain a comprehensive database of substantially all properties within a jurisdiction, in which a unique identifier is assigned to each property.
