Abstract: Disclosed herein are methods for isolating target cells from blood, involving mixing in an open container an undiluted blood sample having a volume of 10 ml or less, and binding agents, wherein each binding agent comprises (A) a primary binding agent comprising an agent capable of binding to at least one cellular epitope on target cells in the undiluted blood sample, (B) a first linker bound to the primary binding agent, to generate binding agent-attached target cells in the undiluted blood sample; contacting the binding agent-attached target cells in the undiluted blood sample with a plurality of buoyant reagents that include a second linker capable of binding to the first linker to generate an undiluted buoyant reagent-attached target cell mixture; diluting the undiluted buoyant reagent-attached target cell mixture by at least 20% to produce a diluted buoyant reagent-attached target cell mixture; applying a vectorial force, such as centrifugal force, to the diluted buoyant reagent-attached target cell mixtu

Abstract: A reader for a lateral flow test device includes a tray or drawer, extendable from the reader, which receives the test device. The tray includes a calibration test pattern affixed or printed thereon placed proximate to the test device and in alignment with the axis of the test device. As the tray is closed and the test device is inserted to the reader, the calibration test pattern is first read by an optics unit including a photodiode. The resulting photodiode output provides a calibration curve S that the reader then uses to correct for any non-linear response of the reader's optical or electronic systems, thus insuring that every reader will yield the same readout for a given test cartridge, despite reader-to-reader variations or reader degradation with time. One use of the reader is for detection of SARS-CoV-2 infection.

Abstract: Disclosed herein are methods for contacting in a closed container a host liquid including target cells, microbubble reagents comprising gas-core lipid-shelled microbubbles, and one or more antibodies or other ligands that bind to cell surface molecules on the target cells, wherein the one or more antibodies or other ligands are bound to the target cells or the microbubbles, wherein the contacting under conditions to produce target cells linked to microbubbles via the one or more antibodies or other ligands and activating the target cells to generate activated target cells.

Abstract: Disclosed herein are cell separation devices, methods and systems, as well as compositions and reagents for use in cell separation methods.
