Enabling Research By Provision of Chemical Tools Poster

The Tocris chemistry team has considerable chemistry knowledge and skill which it has recently been applying to the generation of new chemical probes from known tools and compounds to help answer biological questions. This poster presents some of the work carried out by Tocris scientists and focuses on two areas: the generation of libraries of chemical building blocks to support Degrader (PROTAC) research and the development of a fluorescent probe to study integrin biology.
