Advanced Western Blotting Solutions for Targeted Protein Degradation & Drug Discovery

Simple Western™ provides you critical information to run quantitative DC50 curves with a high throughput workflow while providing you reproducible and quantifiable data. Simple Western assays and their automated Western blotting capabilities enhance accuracy, ensure data quality, and deliver results. Our systems integrate easily in PROTAC® screening assays while providing you the flexibility of seamless transferability of methods and an open platform.

Jess Instrument

Precise, Quantitative Data for the Accurate Determination of DC50 and Dmax Values

Boost your screening workflow with Simple Western systems, while running up to 96 samples in a single run! In this application note, 120 samples were screened in just two overnight runs to provide highly quantitative data which allows for an accurate determination of DC50 and Dmax. Here, off-the-shelf antibodies from Novus Biologicals and PROTAC® degraders from Tocris were used to automatically profile PROTAC®-induced Cereblon neosubstrate degradation.

Validating Targets For Targeted Protein Degradation Using dTAG

dTAG degradation technology offers a generalizable strategy to degrade, in principle, any intracellular protein of interest. The broad applicability that it offers makes this a useful strategy for exploration and validation of targets, particularly in the context of new Degrader development programs.

Monitoring Target Engagement in Drug Discovery

In drug discovery, confirmation of in-cell target engagement is a critical component of the drug development process. Confirming that a drug candidate engages its proposed target in the cell and determining the concentration at which it exerts the desired effect(s) fulfill fundamental criteria for translation to activity and efficacy in its target tissue. Thermal shift assays (TSA) are regularly used by industry and academia to uncover or confirm interactions using purified proteins. Recently, this type of assay has been adapted to a cellular format and is called the cellular thermal shift assay (CETSA). Importantly, by upgrading from a biochemical to a cellular system, biological relevance is preserved.

Dr. Matias Casás Selves, Research Scientist, Drug Discovery Program, Ontario Institute for Cancer Research, developed a CETSA-Simple Western assay to monitor protein stability during drug discovery. This application note highlights quantitative and reproducible CETSA data generated with Simple Western (CETSA-Simple Western). This assay verifies drug–target binding, and given its quantitative nature, the half maximal inhibitory concentration (IC50) is also calculated.
