  • Publication number: 20200114345
    Abstract: Surfaces contactable by a bulk liquid for use in particle isolation are described. The surfaces comprise a plurality of ribs spaced apart to capillarily retain a portion of the bulk liquid and particles of interest therebetween. Collectively, the portion of the bulk liquid retained by the plurality of ribs on the surface forms a liquid film. The one or more particles received within the space and enveloped by the liquid film may be protected from one or more forces exerted by a draining meniscus passing over the surface.

  • Publication number: 20200017825
    Abstract: The present disclosure relates to improved supplements, culture media and methods for enhancing the survival or proliferation of mammalian stem cells. In particular, adding a lipid supplement, such as a lipid-enriched carrier (e.g. a lipid-enriched albumin), to the culture medium may enhance the survival and/or proliferation of the stem cells by at least 5% to 65% as compared to a culture medium that does not contain the lipid supplement.

  • Publication number: 20190161748
    Abstract: An apparatus and method for magnetic separation are provided. The apparatus and method can be used to separate magnetically linked targets from unlinked targets in a suspension. The apparatus has a two-dimensional magnetic array that includes a plurality of one-dimensional magnetic arrays that each define a Halbach array. The one-dimensional arrays are positioned adjacent to one another, and the magnetic fields defined by the plurality of one-dimensional arrays are oriented in the same direction across the array surface. A housing can support the plurality of magnetic elements of the two-dimensional magnetic array. The housing defines a container receiving surface on which a container is receivable adjacent the surface of the magnetic array. A container with a plurality of magnetically linked targets and unlinked targets may be positioned in proximity to the array surface to separate the magnetically linked targets from unlinked targets in the suspension.

  • Patent number: 10124337
    Abstract: Various embodiments are described herein for controlling the self-assembly process of paramagnetic particles and the final particle cluster size using a liquid-liquid interface. The number of paramagnetic particles within a particle cluster and coating at the liquid-liquid interface may be controlled by systematically varying the strength of an applied magnetic field gradient and the interfacial tension of the liquid-liquid interface.

  • Patent number: 7919319
    Abstract: One or more cells can be cultured when confined in space by barriers. The distance between barriers can be comparable to the size of a cell to be cultured. The space between barriers can also be sufficiently small to allow control of cell properties or monitoring of the cell(s) cultured therein. The cell(s) may be confined completely or may be mobile between two opposing barrier surfaces. The gap between two opposing barriers may be sufficiently narrow to allow only a monolayer of cells to be cultured. A barrier can be transparent. The surfaces of the barriers may have one or more pre-selected characteristics that mimic the characteristics of a biological niche of the cells(s). The number of cells in a cell culture may be limited to permit control of properties of individual cells. The cultured cell(s) may be monitored, such as imaged, over a long period of time, using standard bright field or fluorescent imaging techniques.

  • Patent number: 5874308
    Abstract: Methods and compositions are provided for in vitro expansion of growth factor dependent cells. Expansion is effected through the use of growth factor conjugates that include a growth factor such as a steel factor and a polysaccharidase substrate binding region. The conjugates are immobilized by binding of the substrate binding region to a substrate of the polysaccharidase in a growth chamber for the cells.
