Claim 0:
1. A kit for conducting an assay, comprising:
a) a substrate comprising a plurality of microwells, each of said microwells having an opening and a bottom, wherein said opening has a draft angle of at least 10 degrees; and
b) a plurality of beads, wherein said beads (i) each comprise a ligand adapted to capture a target analyte, (ii) are wider than said bottom of said microwells, and (iii) are adapted to seal said microwells, wherein said beads and said micro wells are geometrically paired such that only one bead in said plurality of beads can anchor within one microwell in said plurality of microwells;
wherein said substrate and said beads are adapted to permit (iv) the removal of said beads from said substrate after said beads have anchored within said microwells, and (v) the detection of binding of said ligand to said target analyte after said anchored beads have been removed from said microwells.
