Chemical probes

Small-molecule chemical probes are important tools that are widely used by scientists to modify – usually to inhibit – the activity of individual proteins in isolated cells or organisms and hence to determine their function.

Chemical probes are also used to test the role of a particular protein in diseases such as cancer, and to help validate that protein as a target for future drugs.

Probe Miner, a publicly available, free-to-use web-based resource, was created by scientists at The Institute of Cancer Research, London, and is the first publicly available, large-scale objective resource on chemical probes.

The ICR is also a co-founder of the Chemical Probes Portal, an open-access online resource which provides expert reviews of chemical probes for use in biomedical research and drug discovery.
