Activity-based assessment of an engineered hyperthermophilic protein as a capture agent in paper-based diagnostic tests

Abstract

This journal is © The Royal Society of Chemistry. Antibodies have traditionally served as the affinity reagents of choice in point-of-care diagnostic biosensors. However, this class of proteins is not ideally suited for this use, being poorly characterized and prone to thermal denaturation. Here, we present an activity-based assessment of an alternative engineered binding protein in a cellulose-based assay.
