On quality criteria for covalent and degrader probes

Molecular Design

Regardless of whether binding to target is covalent or non-covalent, the concentration and affinity of substrates (as well as cofactors such as ATP) need be properly accounted for when interpreting effects of chemical probes in cell-based assays. As measurement of k.inact/K.i values for a covalent chemical probe.]
