Products and Services for Targeted Protein Degradation
Target Validation and Exploration
Target Validation, the process of establishing that a potential molecular target is involved in a physiological function or disease process, is a key step in the development of new Degraders, as well as for drug discovery and biological research. Our TAG Degradation platform offers a differentiated method for target validation, using targeted protein degradation to reversibly knockdown a potential protein target and enable exploration of the downstream phenotype.
Degrader Design and Synthesis
Targeted protein degradation can be achieved using small molecule Protein Degraders, such as PROTAC molecules. Bio-Techne provides a toolbox of products and services to support your Degrader Design and Synthesis program and save you time and money, including our PROTAC Panel Builder online tool; a large range of off-the-shelf Degrader Building Blocks; and tools for new E3 ligase ligand discovery.
Assays for Targeted Protein Degradation
Successful development of small molecule Protein Degraders for targeted protein degradation requires an array of assays to address a specific and differentiated set of questions aimed at characterizing aspects of Degrader activity. The assay workflow should explore: target engagement and ternary complex formation induced by the Degrader; ubiquitination of the target protein; as well as target degradation and its downstream consequences. Multiple orthogonal assays will maximize the chance of successful Degrader development.
E3 Ligase and Ubiquitin Proteasome System Biology
Bio-Techne through the R&D SystemsTM brand provides a wide range of products to help you explore and characterize ubiquitin biology. The rapidly expanding portfolio includes highly active E3 Ubiquitin Ligases, including SKP2, VHL, Cereblon (CRBN) and DCAF proteins, as well as assay kits and components, and antibodies. We also provide Cullin-Rbx complexes (including neddylated cullins) that can be coupled to your purified substrate binding complexes to generate active ligases.
Custom Services for Targeted Protein Degradation
Bio-Techne offers a unique portfolio of custom services to support your PROTAC® discovery and development and target validation programs. Harness our expertise in custom chemistry to develop active degraders to knock down your target of choice or custom building block panels. We also offer custom E3 ligase development services enabling you to build your own assays to investigate ubiquitination, and custom knock-in cell lines expressing your target protein of interest as a fusion with a "TAG" protein for use within our TAG degradation platform.

Background Information
How do Degrader molecules work?
Targeted Protein Degradation is a technique that uses heterobifunctional small molecule Degraders, to bring about efficient and highly selective degradation of a target protein of interest. Targeted protein degradation enables investigation of the downstream consequences of protein knockdown and provides an easy-to-use method for target validation.
Bio-Techne provides small molecule Protein Degraders, including PROTAC molecules and TAG Degraders (dTAG/aTAG/BromoTag). PROTAC molecules comprise a ligand that binds a target of interest joined by a linker to an E3 ligase ligand. A ternary complex is formed by the simultaneous binding of the Degrader to the target protein and the E3 ligase, which initiates ubiquitination of the target protein and its subsequent destruction by the proteasome. TAG Degraders work on a similar principle, but comprise an E3 ligase ligand linked to a compound that binds a fusion of a TAG degron with a target protein of interest. These Degraders enable the knockdown of proteins for which there are no known ligands.
Bio-Techne supplies a range of other products and services to support Targeted Protein Degradation studies, including Degrader Building Blocks to enable you to create your own Degraders, as well as Ubiquitin-Proteasome System (UPS) Proteins and Assays, Assays for Protein Degradation, and Custom Degraders Services.
Why Use Degraders?
Small molecule Degraders offer several advantages over genetic manipulation for target protein knockdown:
- Degraders are cell-permeable, are suitable for use in vivo and in vitro, and can be applied directly to cells with no need for transfection or expression vectors.
- They are applicable to multiple cell lines with no requirement that cells are easily transfectable
- The duration of effect is adjustable and reversible on compound washout
- They have a catalytic mode of action repeatedly engaging and directing ubiquitination of target molecules, allowing use at sub-stoichiometric concentrations.
