Affinity-based ranking of ligands for DPP-4 from mixtures

Affinity-based selection strategies have recently emerged as a complement to traditional high throughput screening for the rapid discovery of lead compounds for the large number of protein targets emerging from--omics technologies. Herein, we describe a method for the ranking of mixtures of ligands by affinity selection and apply it to rank order a set of inhibitors for the enzyme dipeptidyl peptidase IV.
