The specification describes an antibody capture process comprising (i) obtaining a biological sample comprising antibodies, (ii) contacting the biological sample with recombinant pIgR or a dIgA-binding variant, wherein the pIgR or variant binds dIgA and forms a pIgR-dIgA complex. The process may further comprise (iii) directly or indirectly assessing the level of the pIgR-dIgA complex or the level of a complex between pIgR-dIgA and an antigen of interest. There is also an antibody capture process for determining gut wall integrity in a test subject, wherein the level or ratio of SIgA to dIgA is compared to a corresponding level or ratio from a control subject. The specification provides kits embodying the process and recombinant pIgR when used for, or for use, in capturing or detecting dIgA and/or IgM.

Diagnostic, prognostic, therapeutic and screening protocols

The invention provides kits and methods for detecting or monitoring the number of cells in sample. The cell comprises a cell surface associated protein (CSAP) comprising a cytoplasmic (cytosolic) and an extracellular (ecto) domain. The kit comprises: (i) a chromatographic device; and (ii) a CSAP-binding agent. The method comprises: (i) optionally contacting the sample with an agent capable of lysing or permeabilizing CSAP bearing cells; (ii) contacting the sample with a CSAP-binding agent that binds to the cytoplasmic domain of the CSAP; and (iii) directly or indirectly evaluating the level or presence of bound CSAP in the sample.

Method of diagnosis and kit therefor

This invention is directed to diagnostic methods detecting the presence of an antibody to a virus in a sample from a subject and kits for using the methods.
