  • Publication number: 20240424084
    Abstract: We claim vaccines and a method of making vaccines targeted against diseases caused by viruses, including influenza virus and SARS CoV-2, against cancer, and diseases caused by bacteria, fungi, and other biomaterials/diseases that are combatted with an immune response. The mRNA vaccine is injected into the body whereupon the injected mRNA hijacks the translational machinery of the cells to produce an antigen such as a virus spike protein or surface protein (or part thereof) and stimulates an immune response. The mRNA in the vaccine is a mixture of mRNAs and where at least one or more of the RNAs are undirected mutant variants of the parent mRNA. The vaccine is a poly vaccine and provides protection against multiple variants. The vaccine may comprise mRNA species encoding several random undirected mutations directed against unknown variants.

  • Publication number: 20240327898
    Abstract: Methods, devices and kits for sampling, releasing and stabilizing nucleic acid, including RNA and DNA, from virus, bacteria yeast and other cells is described. The released and stabilized nucleic acid may be analyzed and quantified without further sample preparation at the point of care or may be transported to a testing laboratory by shipment and analyzed directly. The nucleic acid, which can be RNA, remains safe and stable so that shipping by normal means including government postal service may be used. In addition, the RNA sample remains stable so that analysis can be performed immediately after receipt of sample or after storage for days, weeks or months. Storage may be at room or ambient temperature or cooler temperatures. The sampling apparatus used to acquire samples can interface with nucleic detection and measurement instrumentation including high throughput, parallel processing instruments.

  • Publication number: 20240301491
    Abstract: Breath liquid particles and vapor are captured in a device presenting a surface and chamber space that condenses or freezes the vapor and aerosol particulates. One or more breaths are exhaled through the device. Capture can be performed on the freezing surface immobilizing water upon contact. The chamber space within the device may freeze or condense liquid breath particles and vapor to collect them. After collection, the liquid is gathered and collected either by draining, scraping, pushing, or centrifugal force. The liquid may be collected and combined with a sample preparation reagent such as a virus lysing reagent, an internal standard, etc. After collection, the sample is separated into a plurality of independently analyzable units for detection and quantification of a target. Analysis may be performed by PCR, qPCR RT-PCR, RT-qPCR, LAMP, RPA or any nucleic acid detection method, lateral antigen mass spectrometry, spectrophotometry or any analytical tool or method.

  • Publication number: 20240091333
    Abstract: Nucleic acid and the nanocomplex reagents are combined to create a vaccine. They are stable and stored separately without degradation. The vaccine components can be stored at a wide range of temperatures. The nucleic acids are stabilized and stored in a column, syringe, vial or chamber as a solid, lyophilized or precipitated. They may be stored on a solid phase surface through electrostatic forces, non-polar interactions, hydrogen bonding, polar interactions or any other mechanism. The solid surface may be media in a column which may be contained in a syringe. Nucleic acid vaccines are prepared by a two-step process. The nucleic acid component is first stabilized and then mixed with nanocomplex reagents, particle forming reagents or other reagents.

  • Publication number: 20240060861
    Abstract: A water solvated chromatography bed is packed into the distal end of a syringe barrel. The syringe pumping piston is modified to be flat to match the top frit structure (that is also flat). The piston pump is pushed into the syringe barrel until the piston is directly above the column top frit. The pumping piston is moved forth quickly to dislodge entrained air in the bed. The piston pump moves directly above the resin bed with no air gap above the bed.

  • Publication number: 20230408383
    Abstract: The present invention relates to the readily automated methods for the separation of biomolecules, such as proteins or nucleic acids. More specifically, the invention relates to a separation device, which includes at least one column provided with a bottom liquid inlet/outlet and adapted to receive a separation media. At least part of an elongated frit has been arranged substantially parallel to the column side walls, segregating the separation media from the bottom liquid inlet/outlet. The elongated frit may be shaped as a tube and should have a porosity that serves to retain separation media within the column during sample processing. Further, the invention relates to a method of separating at least one target molecule from a liquid, which method comprises providing at least one column provided with a bottom liquid inlet/outlet and optionally with a top liquid inlet.

  • Publication number: 20230128571
    Abstract: The present invention is an automated separation system comprised of a liquid handling device and one or more pipette tip columns, wherein the liquid handling device is equipped with two or more nozzles arranged to respectively receive a pipette tip column comprising separation media. Further, the system includes means for applying either high positive or negative pressure to the column inside chamber above the column bed, enabling aspiration and dispensing into and out of each pipette tip column. To enable sealing to the pressures used to move liquid through the column bed without inadvertently ejecting the column from the nozzle during the separation process, each nozzle has been provided with at least one annular protrusion arranged to engage with the inside of a substantially evenly tapered pipette tip column, without any corresponding recess. Each nozzle may be provided with slide ejector to enable the removal of a pipette tip column.
