Abstract:
1. A kit for performing an agglutination assay for detection of an analyte in a sample, the kit comprising: i. a capillary testing device having at least one capillary pathway; ii. a conjugate comprising a soluble hub to which two or more first binding partners are bound, wherein the soluble hub is a soluble polysaccharide having a molecular weight of 250-2,500 kDA wherein each first binding partner has a specific binding site for a first epitope of the analyte whereby upon binding the analyte is presented to the assay as a multi-epitopic entity, and wherein the conjugate is soluble in an aqueous solution; and iii. two or more of a first agglutinable particle each having two or more second binding partners bound to it, wherein each of the second binding partners comprises a specific binding site for a second epitope of the analyte, wherein the first and second epitopes are different from each other; and wherein the kit does not comprise a second agglutinable particle.
