Patent number: 10591473Abstract: An antigen detection method using sandwich immunoassay includes a first reaction step of preparing a sensor chip, which includes a fine flow channel in which a reaction zone having an antigen-capturing antibody immobilized thereon is arranged, a liquid discharge/suction section and a liquid-mixing section, and subsequently feeding thereto a sample liquid so as to allow the antigen-capturing antibody to capture a target; and a second reaction step of allowing a labeling liquid containing a labeling antibody to flow into the fine flow channel so as to label the target. In the antigen detection method, the labeling liquid does not reach the liquid-mixing section. According to the antigen detection method, the accuracy and the repeatability of the target measurement can be improved.Type: GrantFiled: October 22, 2014Date of Patent: March 17, 2020Assignee: KONICA MINOLTA, INC.Inventors: Takanori Murayama, Atsuo Iwashita

Patent number: 10590495Abstract: Methods, devices, and systems for performing polymerase chain reaction (PCR) amplification and melt data acquisition according to a single slug approach in which a single slug in a microfluidic channel fills an entire thermal zone of the microfluidic channel, and the thermal zone used for both PCR temperature cycling and melt data acquisition. A detector may be configured to detect fluorescence from the thermal zone during the PCR temperature cycling for real-time PCR and/or during temperature ramping in the melt data acquisition. Slug position control may be achieved by detecting leading or trailing edges in a slug build target zone into which a slug passes after passing through the thermal zone. The single slug approach may break coupling between one or more events of the PCR amplification and melt data acquisition and enable events to be independently optimized.Type: GrantFiled: February 26, 2018Date of Patent: March 17, 2020Assignee: Canon U.S.A., Inc.Inventors: Johnathan S.

Patent number: 10588987Abstract: The present invention relates to compositions and methods for use in medical diagnosis and patient monitoring. It more particularly relates to a biocompatible gel comprising nanoparticles and/or nanoparticle aggregates, wherein: i) the nanoparticles and/or nanoparticles of said aggregate comprise an inorganic material comprising at least one metal element having an atomic number Z of at least 25, each of said nanoparticles and nanoparticle aggregates being covered with a biocompatible coating; ii) the nanoparticles' and/or nanoparticle aggregates' concentration is of about or less than 0.5% (w/w); and iii) the apparent viscosity at 2 s?1 of the gel comprising the nanoparticles and/or nanoparticle aggregates is between about 0.1 Pa·s and about 1000 Pa·s when measured between 20° C. and 37° C. The composition of the invention typically allows the delineation and visualization of at least 40% of the target biological tissue when said tissue is observed using an X-ray imaging equipment.Type: GrantFiled: June 19, 2014Date of Patent: March 17, 2020Assignee: NANOBIOTIXInventors: Laurence Poul, Laurent Levy, Celine Berjaud, Matthieu Germain, Agnes Pottier

Patent number: 10591392Abstract: A biopsy-sized tissue sample is stained for quick imaging. A significant amount of permeation enhancer is included in a mixed solution of permeant enhancer, fixative or dehydrant, and one or two fluorescent dyes to simultaneously dehydrate and dye the tissue sample. The permeation enhancer, e.g., 10% to 50% in the mixed solution, achieves an image of dyed tissue in the contacted tissue sample at a depth of at least 200 um within no more than 1.5 hours. One of the fluorescent dyes is a fluorescent nuclear dye such as DAPI, SYTOX green, acridine orange, propidium iodide, or a Hoechst dye. The other fluorescent dye is a fluorescent protein dye such as eosin or rhodamine B. The tissue sample is cleared with a clearing agent having a refractive index of at least 1.4[R2], e.g., using BABB. The mixed solution may further include Chloroform or other morphology preservative.Type: GrantFiled: July 3, 2014Date of Patent: March 17, 2020Assignee: APPLIKATE TECHNOLOGIES LLCInventors: Richard Torres, Michael Levene

Patent number: RE47983Abstract: Provided herein are compositions and methods for identifying or quantitating one or more analytes in sample. The composition can comprise an affinity molecule reversibly conjugated to a label moiety via a double-stranded nucleic acid linker or via an adaptor molecule. The affinity molecule and the label moiety can be linked to different strands of the double-stranded nucleic acid linker. Compositions can be used in any biological assays for detection, identification and/or quantification of target molecules or analytes, including multiplex staining for molecular profiling of individual cells or cellular populations. For example, the compositions can be adapted for use in immunofluorescence, fluorescence in situ hybridization, immunohistochemistry, western blot, and the like.Type: GrantFiled: June 28, 2018Date of Patent: May 12, 2020Assignee: University of Washington through its Center for CommercializationInventors: Xiaohu Gao, Pavel Zrazhevskiy
