Abstract
Methods, products, and kits for identifying an analyte in a sample are provided. One embodiment of a method for identifying an analyte in a sample includes combining the sample with a first reactant capable of specifically coupling to the analyte. The first reactant is coupled to beads. The method also includes combining additional reactant with the beads. The additional reactant is capable of specifically coupling to the analyte or a second reactant coupled to an analyte. An enzyme is attached to the additional reactant. In addition, the method includes combining a substrate with the beads. The substrate is capable of specifically interacting with the enzyme to form a modified substrate. If the substrate interacts with the enzyme attached to the beads via the additional reactant, the solubility of the substrate changes causing the modified substrate to bind to a surface of the beads and/or the reactants bound to the beads. The method further includes identifying the analyte in the sample by detecting the modified substrate bound to the surface of the beads and/or the reactants bound to the beads.
