  • Patent number: 11453864
    Abstract: Many strains of the human pathogen Neisseria meningitidis carry a compact Cas9 (NmeCas9) that can serve to limit genetic exchange via natural transformation. Cas9 orthologues (including NmeCas9) have recently been adopted for RNA-guided genome engineering and DNA binding, adding to the need to define better their activities and properties. The present invention examines DNA cleavage activities and substrate requirements of NmeCas9, including a set of unusually complex PAM recognition patterns. Unexpectedly, NmeCas9 is found able to cleave single-stranded DNA (ssDNA) targets in a manner that is RNA-guided but both PAM- and tracrRNA-independent. Beyond the requirement for guide-target pairing, this activity has no apparent sequence requirements, and the cleavage sites are measured from the 5? end of the DNA substrate's RNA-paired region.

  • Patent number: 11385226
    Abstract: An assay system is provided of great sensitivity and portability where the presence of a specific target in a sample, as well as its concentration (qualification and quantification) is detected by reason of a potential or voltage in a closed circuit, built up a redox reaction. The reaction is produced by binding a capture moiety to an enzymatic redox reaction partner, allowing the capture moiety to bind to any target in the sample. In a homogenous assay, the method further comprises washing any such bound target. The bound target may be immobilized through use of a second capture moiety. Substrate for the enzyme is then added. The action on the substrate by the enzyme generates electrons, creating a potential across an anode and cathode which may be separated by a membrane.

  • Patent number: 10564152
    Abstract: Methods for detecting antigen-specific antibodies in a biological sample are described. The disclosed methods can be used for the diagnosis of a variety of autoimmune and infectious diseases. The methods use a neodymium magnet to efficiently isolate immune complexes. The disclosed methods are rapid, highly specific and sensitive, require very small volumes of biological sample, and do not require the use of radioactivity. With these advantageous features, the disclosed methods are amendable for point-of-care testing (POCT), which is currently not available for the detection of autoantibodies associated with autoimmune disease or for the detection of many pathogen-specific antibodies.

  • Patent number: 10448514
    Abstract: A method produces a conductive paste comprising 15-20% by weight of PDMS and 80-85% by weight of metallic micro-nano particles, wherein the conductive paste is obtained by repeated addition of singular doses of PDMS to a heptane diluted PDMS low viscosity liquid containing the metallic micro-nano particles, wherein the heptane fraction is allowed to evaporate after addition of each of the singular doses of PDMS. A method forms a conductive path on a support layer, wherein the conductive path is encapsulated by an encapsulation layer comprising at least one via through which at least one portion of the conductive path is exposed, the method comprising filling the at least one via with the conductive paste.

  • Patent number: 10345309
    Abstract: The present invention provides biological markers associated with gastric cancer. In particular, the present invention provides a method of diagnosing gastric cancer (GC) in a subject, the method including: measuring an expression level of one or more proteins in the subject, wherein the one or more proteins are selected from the group consisting of vitamin D binding protein (VDBP), clusterin, insulin like growth factor binding protein complex acid labile subunit (IGFALS), and afamin; comparing the expression level of the or each protein in the subject to a reference expression level for the or each protein; and diagnosing GC in the subject on the basis of the comparison.
