Biological Activity for dTAG-Biotin

dTAG-Biotin is an affinity probe for mutant FKBP12F36V proteins. Comprises the ligand ortho-AP1867, selective for F36V single-point mutated FKBP12, joined by a PEG3 linker to biotin. It can be used for chemical biology studies such as proteomics, enrichment studies, dimerization experiments, and assay validation.

Targeted Protein Degradation Poster

Targeted Protein Degradation Poster

Degraders (e.g. PROTACs) are bifunctional small molecules, that harness the Ubiquitin Proteasome System (UPS) to selectively degrade target proteins within cells. They consist of three covalently linked components: an E3 ubiquitin ligase ligand, a linker and a ligand for the target protein of interest. Authored in-house, this poster outlines the generation of a toolbox of building blocks for the development of Degraders. The characteristics and selection of each of these components are discussed. Presented at EFMC 2018, Ljubljana, Slovenia

Validating Targets for TPD Using dTAG Poster

Validating Targets for TPD Using dTAG Poster

The dTAG platform offers a generalizable strategy to degrade, in principle, any intracellular protein of interest (POI) and is a useful strategy for exploration and validation of targets. This poster presents a workflow solution for target validation, from custom TAG knock-in cell-lines for your POI, different dTAG Degraders to knockdown you POI, to automated assays for protein degradation using Simple WesternTM instruments. Data are also presented on the use of an antibody that recognizes the TAG domain (FKBP12F36V) for detection of degradation. Presented at TPD Europe, March 2022, London, UK.
