  • Patent number: 10982260
    Abstract: Systems and methods for nucleic acid sequencing are provided. Nucleic acid is fixed in double-stranded linearized stretched form on a test substrate before being denatured into to single stranded form on the substrate to obtain adjacent fixed first and second strands of the nucleic acid. The strands are exposed to a respective pool of a respective oligonucleotide probe in a set of probes under conditions allowing for probes to form a heteroduplex with a corresponding complementary portion of the fixed first or second strand thereby giving rise to a respective instance of optical activity. An imager measures a location and duration on the substrate of this optical activity. The exposing and measuring is repeated for probes in the set of probes thereby obtaining a plurality of sets of positions. The nucleic acid sequence is determined from the plurality of sets of positions through compilation of the positions in the sets.

  • Patent number: 10905782
    Abstract: Compositions and methods for enhancing delivery of molecules, e.g. biological agents, into cells are described. The composition is a conjugate of the biological agent, preferably a nucleic acid analog having a substantially uncharged backbone, covalently linked to a peptide transporter moiety as described. Conjugation of the peptide transporter to a substantially uncharged nucleic acid analog, such as a morpholino oligomer, is also shown to enhance binding of the oligomer to its target sequence and enhance antisense activity.

  • Patent number: 10900069
    Abstract: This disclosure related to methods of detecting mechanical forces required to separate ligand and receptor interactions. In certain embodiments, this disclosure relates to methods of detecting mechanical forces between a ligand and receptor, where the ligand is immobilized on a surface using weaker forces. Ligand-receptor forces lead to dissociation of the ligand that can be detected and amplified. In certain embodiments, the disclosure relates to methods of detecting ligand and receptor interactions comprising linking a ligand to one of two binding partners, wherein the binding partners have attracting forces that are less than the forces between the ligand and a receptor of the ligand such that when the ligand binds the receptor, the binding partners will separate. Separation of the binding partners can be detected.

  • Patent number: 10900965
    Abstract: Disclosed are kits and methods for determining the presence or absence of an antibody of interest in a biological sample of a subject. In particular, the methods may detect either pathological or beneficial antibodies. The method may include the step of contacting a biological sample from a subject with a substrate conjugated to an antigen and an Fc receptor operatively linked to a detectable label. Detection of the label may indicate the presence or absence of an antibody of interest.

  • Patent number: 10894981
    Abstract: The object is to provide a method that enables detection of unknown virus sequences and efficient detection and search of viruses. The method comprises the step of randomly fragmenting an objective double-stranded (ds) RNA to obtain dsRNA fragments; the step of subjecting the obtained dsRNA fragments to a reverse transcription reaction and then performing polymerase chain reaction (PCR) to obtain corresponding DNA fragments; and the step of subjecting the obtained DNA fragments to a sequence analysis operation to determine the sequences. The reverse transcription reaction is preferably started from the 3? ends of the dsRNA fragments.

  • Patent number: 10894978
    Abstract: A method for amplifying a CYP21A2 gene and/or a CYP21A2 gene chimera from a sample is provided. In some embodiments, the method may comprise amplifying a product from a sample comprising human genomic DNA by PCR using a forward primer that is complementary to a sequence that is duplicated in a bimodular human RCCX locus and a reverse primer that is complementary to a sequence that occurs only once in the bimodular human RCCX locus at a position that is downstream of the CYP21A2 gene. Methods for analyzing the amplification product are also provided.

  • Patent number: 10884007
    Abstract: A flow cytometry apparatus includes a flow cytometer having a suction or negative-pressure intake probe, a support for a microplate having a plurality of sample wells, and motive elements operatively connected to at least one of the probe and the support for moving the intake probe and the support relative to one another so that the intake probe is sequentially aligned with different sample wells of the microplate. The apparatus has no fluid pumping elements between the support and the flow cytometer so that a bubble-separated sample stream is forced to the flow cytometer solely by virtue of a negative pressure communicated via the intake probe.

  • Patent number: 10876168
    Abstract: The present invention discloses a tumor molecular detection/diagnostic reagent, which takes excrement as a detection sample and includes an SDC2 gene methylation detection reagent. The methylation level of the SDC2 gene detected in the excrement has an extremely high relevance to the onset of the colorectal cancer. The sensitivity of the SDC2 gene in the excrement is 87 percent and the specificity is up to 98 percent or even higher than that in tissue.
