  • Publication number: 20240076637
    Abstract: Methods for labeling and imaging the accessible genome using a transposase are disclosed. In some embodiments, a bifunctional transposase complex or transposome is used to insert adaptors comprising chemical tags selectively at accessible sites in the genome where active regulatory DNA is located. Various chemical tags can be used for labeling DNA at insertion sites, including, for example, fluorescent dyes for fluorescence imaging, metal particles for electron microscopy or magnetic manipulation of DNA, isotopic labels, or biotin or other ligands, haptens, substrates, or inhibitors that are recognized by streptavidin, antibodies, enzymes, or receptors. Labeling DNA in this manner can be used to provide spatial information regarding the positioning of regulatory DNA in the genome and makes possible the imaging and sorting of cells based on the status of their regulatory DNA.

  • Patent number: 10135436
    Abstract: A reset circuit includes a detect circuit, a maintain circuit and an output circuit. The detect circuit and the maintain circuit are coupled to the output circuit, wherein the detect circuit is arranged to detect at least an input power provided to a loading, and make the output circuit output a reset signal when a voltage of the input power goes into an abnormal state, and the maintain circuit is arranged to stop the output circuit from outputting the reset signal when the loading is in a standby state. The reset circuit is applied within an electronic device.
