Abstract: A method includes conveying a detection solution containing a target amplicon into a detection module of a molecular diagnostic test device. The detection module includes a detection surface including a series of capture probes to which a first portion of the target amplicon is bound when the detection solution is conveyed. A first reagent formulated to produce a visible signal indicating a presence of the target amplicon is then conveyed into the detection module. The first reagent is bound to a second portion of the target amplicon when the first reagent is conveyed. A second reagent is conveyed into the detection module. The second reagent includes a precipitating substrate formulated to catalyze the production of the visible signal by producing an insoluble colored product when the second reagent is in contact with the first reagent. The method includes viewing the visible signal via a transparent portion of the detection module.

Abstract: Phosphorylated protein (i.e., phosphoprotein) affinity resins and methods for making and using the same are provided. The subject resins include a substrate bonded to aspartate-based tetradentate ligand/metal ion complexes, where the tetradentate ligand/metal ion complexes have high specificity for phosphorylated amino acids. The subject resins find use in a variety of different applications, including phosphoprotein enrichment applications. Also provided are kits and systems that include the subject resins.
