Affinity Selection Mass Spectrometry
Our dedicated ASMS (Affinity Selection Mass Spectrometry) screening team offers clients this unique platform for the identification of small molecules capable of binding to the active sites of target proteins. These active small molecules will be the perfect starting point for your drug discovery programs. Our high quality service supports both established and newly emerging targets and is backed by access to small molecule libraries, automated operational systems, sensitive high resolution mass spectrometry devices and efficient data processing software.
