X-Chem is a World Expert in the Science of Affinity-Mediated Selection

Our techniques have their roots in Nobel-prize-winning science, improved and expanded to provide a powerful discovery engine. At X-Chem, we design selection experiments that produce the potent, novel and selective hits that drive successful drug discovery.

In a selection experiment, billions of small molecules are screened for affinity against your target of interest. By performing multiple selection experiments with varying conditions in parallel, we can characterize hits on the basis of potency, selectivity and site of action. X-Chem scientists are experts at designing selection campaigns that target the exact profile desired for your drug discovery program. In addition, X-Chem has pioneered novel selection methods such as covalent and cellular selection techniques that provide added power and flexibility.
