Affinity selection (AS)-MS is a label-free binding assay technology for the analysis of interactions between targets and small drug molecules, which does not require modification of targets or compounds. AS-MS technology has been used in drug discovery research for more than 10 years, and is currently one of the most important affinity-based screening techniques. As such, it may be the driving force for novel small molecule drug discovery. This review introduces the principles of AS-MS technology and its use in high-throughput screening (HTS), then discusses strategies for its use in drug discovery and its application in target identification.
