Proteolysis Targeting Chimeras (PROTACs) have emerged as novel therapeutics to target the undruggable proteome. PROTACs are heterobifunctional small molecules that both simultaneously bind to a target protein and a ubiquitin (Ub) E3 ligase. This subsequently leads to ubiquitination and degradation of the target protein. The In vitro ubiquitination kit has been developed to establish a high throughput approach that can accurately predict PROTAC efficiency by monitoring the protein’s intrinsic ability to get ubiquitinated. We offer this kit for three E3 ubiquitin ligases: Cereblon, VHL, and HDM2 to monitor PROTAC mediated ubiquitination for target of choice.
New assay plate developed for colorimetric detection allows for quantitative measurement using absorbance-based plate readers. Colorimetric readouts (650nm, 480nm) are more consistent day-to-day than luminescent-based detection methods, fast, and easy to use.
