Chemical Probes
Chemical Probes
Potent, selective and cell-permeable inhibitors of protein function ("chemical probes") are valued reagents in both fundamental and applied biological research, and they are essential for the early stages of drug discovery by allowing preclinical target validation in both academic and industrial laboratories.
SGC chemical probes are open-access reagents that are meant to be used by the biomedical research community with no restrictions on use. To acquire a sample, follow the links on the webpage of your desired chemical probe. You can sort the table by clicking the column headers.
The SGC probes set is complemented by the donated probe set

Chemical Handles
This versatile modality can be used to develop tools for proximity-inducing chemistry, tracers for target engagement assays, PROTACs, chemical inducers of degradation, and pull-down reagents. Handles bind their target with Kd < 1 micromolar. Their selectivity and cell activity has not been determined.
