Recombinant proteins are useful tools in understanding protein-protein interactions, such as receptor-ligand binding and extracellular matrix interactions. Therapeutic strategies often focus on these interactions. A common binding assay, known as a functional ELISA, involves the attachment of a recombinant receptor extracellular domain to a microplate, followed by the addition and detection of the ligand. Carrier-free proteins should be used when coating the microplate to avoid competition of the recombinant protein and carrier protein during the plate coating process.
Additionally, we have SPR (PPI, protein-protein interaction) services available. Please inquire.

Targeted Protein Degradation (TPD) refers to the use of heterobifunctional small molecule Degraders (e.g. PROTACs™) to achieve knockdown of
a protein of interest. These small molecules are composed of an E3 ligase ligand and a target protein ligand, joined by a linker. Binding of both
ligands results in the formation of a ternary complex between E3 ligase and target protein, resulting in polyubiquitination of the protein and its
subsequent degradation by the proteasome.
Tocris provides a selection of commercially available building blocks to support Degrader research and development including functionalized
E3 ligase ligands and E3 ligase ligands conjugated to common linker groups. Tocris also offers a custom service for the design and synthesis
of Degrader building blocks for your targeted protein degradation research. Additionally, we can partner with your discovery project for the
custom design and synthesis of active Degraders.
