Abstract: Described herein are methods and compositions for modifying a mammalian cell plasma membrane to retain secreted antibodies, capturing antibodies produced by the cells and sorting antibody producing cells according to antibody specificities or antibody quantities. These methods and compositions may be particularly useful for biological and medical applications. The methods may include modifying cell membranes from a population of antibody producing cells by inserting a membrane anchor into the cell membranes, a generic antibody capture molecule attached to the cell anchor, capturing antibodies produced by the cell, and detecting and dispending cells according to antibody specificities or antibody quantities with a microparticle sorting and dispensing apparatus.

Abstract: A removable cartridge for a microparticle sorter. The removable microparticle sorter cartridge may be used with a microparticle sorter to sort and collect microparticles using a series of fluidic channels having a specific orientation and geometry and a series of inlets/ports. By adjusting the flow rates within the channels and applying either positive or negative pressures at the various inlets, microparticles may be sorted based upon a pre-determined characteristic. The disposable microparticle sorter is intended to be used with a corresponding microparticle sorting apparatus.

Abstract: Methods and apparatuses for sorting and isolating individual microparticles (e.g., cells) by bulk sorting groups of microparticles into groups containing one or more microparticle having a desirable characteristic (e.g., a label such as a florescent label, shape, size, etc.), and then sorting the individual microparticles with this desired characteristic individual particles.

Abstract: Apparatus and methods for sorting and dispensing microparticles using a flow switch mechanism wherein changing flow rate into the flow switch changes flow path. The present invention is well-suited for precisely sorting microparticles, such as cells, for applications such as cell line development, monoclonal antibody selection and single cell research, etc.
