Fully integrated hand-held device to detect specific nucleic acid sequences
A fully integrated and disposable point-of-care device for detecting a target nucleic acid is provided. The device comprises: an extraction chamber adapted to receive a biological sample, wherein said extraction chamber comprises means to extract and lyse the sample to release nucleic acid; a first amplification chamber in communication with the extraction chamber, wherein said amplification chamber comprises means to trigger nucleic acid amplification of a target nucleic acid sequence to occur; and a detection chamber in communication with the amplification chamber, wherein said detection chamber comprises means to detectably label the target nucleic acid and means to detect a signal associated with labeled target nucleic acid, or a single chamber for amplification, detection and identification of multiple nucleic acid sequences.
Contiguity particle formation and methods of use
Embodiments of systems, methods, and compositions provided herein relate to hollow beads encapsulating single cells. Some embodiments include performing multiple co-assays on a single cell encapsulated within a hollow bead, including nucleic acid sequencing, preparing nucleic acid libraries, determining methylation status, identifying genomic variants, or protein analysis.
CELL CULTURE BOTTLE
The invention relates to a cell culture bottle for adherent cells (e.g. human mesenchymal stem cells), comprising: a vessel; an internal cylinder, which has an internal Archimedes screw; an internal central tube, through which liquid can flow; and at least one wall arranged around the central tube. This arrangement provides an enlarged inner surface for the growth of the cells and for the reliable mixing of the fluid. The cell culture bottle is formed as a single piece and can be simply and economically produced as a disposable device by means of additive manufacturing.
SYSTEM AND METHOD FOR BUOYANT PARTICLE PROCESSING
A system for buoyant particle processing includes: a reaction vessel, a stirring mechanism, a set of one or more pumps, and a filter. The system can additionally or alternatively include a set of pathways and/or any other suitable component(s). A method for buoyant particle processing includes: stirring the contents of a reaction vessel; washing a set of buoyant particles; and filtering the contents of the reaction vessel. Additionally or alternatively, the method can include any or all of: preprocessing the set of buoyant particles; adding a set of inputs to the reaction vessel; washing the set of buoyant particles; repeating one or more; and/or any other suitable process(es).
Microcarrier filter bag assemblies and methods of use
A filter bag assembly includes a flexible bag bounding a compartment that is configured to hold a fluid. An inlet port and an outlet port are each secured to the flexible bag so as to communicate with the compartment. A porous filter sheet is disposed within the compartment of the flexible bag so that fluid entering the compartment through the inlet port must pass through the filter sheet before exiting the compartment through the outlet port. A first retention seal secures the porous filter sheet to a portion of the flexible bag within the compartment, the first retention seal having an outer perimeter edge that forms an annular continuous loop.
THREE-DIMENSIONAL CULTURE METHOD FOR LARGE-SCALE PREPARATION OF STEM CELLS
A three-dimensional culture method for large-scale preparation of stem cells, comprising a three-dimensional microcarrier-based cell resuscitation method, a three-dimensional microcarrier cell culture-based in situ passage method, a three-dimensional microcarrier in situ freeze preservation method for cells, a three-dimensional microcarrier cell adsorption culture method, a method for harvesting cells on a three-dimensional microcarrier, a method for sampling cells cultured on a microcarrier, and a three-dimensional microcarrier-based cell large-scale expansion method.
METHODS AND DEVICES FOR ASEPTIC DRY TRANSFER
Devices and systems for product transfer, such as a dissolvable microcarriers, are described. In one example, the product delivery device may include an inlet port; a conical section that may include a wide end and a narrow end; an outlet port flush with the narrow end of the conical section and extending away from the conical section; and a securement feature configured to connect the wide end of the conical section to a container. In another example, a system for aseptic dry product delivery may include a container at least partially filled with the aseptic dry product; a product delivery device; a pressure source connected to an inlet port; and a receiving vessel where the aseptic dry product is collected.
METHODS FOR ENCAPSULATING AND ASSAYING CELLS
In biosciences and related fields, it can be useful to study cells in isolation so that cells having unique and desirable properties can be identified within a heterogenous mixture of cells. Processes and methods disclosed herein provide for encapsulating cells within a microfluidic device and assaying the encapsulated cells. Encapsulation can, among other benefits, facilitate analyses of cells that generate secretions of interest which would otherwise rapidly diffuse away or mix with the secretions of other cells.
BIOREACTOR WITH VOLUME-ADJUSTABLE PACKING LAYER
There is provided a bioreactor including: a chamber unit having an accommodating space therein; an upper fixing member and a lower fixing member that are disposed at respective planes perpendicular to a central axis of the chamber unit inside the chamber unit and are movable in a central-axis direction of the chamber unit; and a filling layer that is formed in a space between the upper fixing member and the lower fixing member inside the chamber unit and contains a plurality of carriers.
Culture device, culture system, and culture method
This culture device comprises: a culture container which houses cells, magnetic particles and a culture medium; a temperature adjustment unit for adjusting the temperature of the culture container; a magnet which is provided to the outside of the culture container; a magnetic force adjustment unit for adjusting the magnetic force of the magnet; and a control unit for controlling the operation of the magnetic force adjustment unit. The magnetic force adjustment unit adjusts the magnetic force of the magnet, thereby holding magnetic particles and cells in a predetermined region within the culture container, or dispersing the magnetic particles and cells within the culture container.
