    Abstract: The invention relates to cell-based methods for diversifying, expressing and selecting binding molecules, e.g., antibodies, and target molecules to which they bind, all of which are expressed in the same cell. The target molecule can be a member of a ligand binding pair comprising a cell-surface expressed ligand binding receptor molecule and its cognate ligand, which interact within the cell. The methods provide retaining either the antibody or its target in a cell organelle as the site of binding and interaction. By performance of the methods, the binding or non-binding of the antibody to its target molecule within the cell produces a cell phenotype that is detectable at the cell surface via high throughput assays, e.g., flow cytometry. The methods are particularly useful for generating, recovering and providing antibodies that have optimal target molecule binding properties or activities for potential therapeutic use. Methods for generating diversity in such antibodies are also provided.

    Abstract: Detection of the presence or absence of, RH positive cells in a mixed population with Rh negative cells, as is found in a fetal maternal hemorrhage (FMH). The novel methods utilize gravitational forces or applying magnetic forces to reactive magnetic particles to isolate, distinguish and quantify cells.Particles aggregate and are pulled or settle by gravity through a transparent separating solution into a measuring zone where the volume of Rh positive cells can be measured. Rh positive cell volume is correlated to the volume of the original blood sample as an indication of the number of doses of RhIG needed to be administered to the mother to prevent subsequent Rh immunization.

    Abstract: Methods and systems for selectively capturing analytes, such as cells, e.g., circulating tumor cells (CTCs), from fluid samples are disclosed. The methods include contacting the sample with an analyte binding moiety that selectively binds to the analytes; optionally separating first components of the sample including a majority of the analytes bound to the binding moieties from second components of the sample using size-based separation, e.g., in a microfluidic channel; adding to the first components of the sample a plurality of binding agents under conditions that enable a plurality of the binding agents to be linked to the analyte binding moieties to form multivalent tagging agents bound to the analyte; passing the first components of the sample past a surface to which is attached a plurality of capture agents that selectively bind to the binding agents; and capturing the analytes by providing conditions that enable the multivalent tagging agents bound to the analytes to bind to one or more of the capture agents.
