E2 SELECT Profiling & Selection Kit

The E2 SELECT™ Profiling & Selection Kit allows for assessing the E2-E3 functional relationship. Therefore, it allows for identifying the optimal E2-conjugating enzyme for an E3 ligase of interest. The assay is based on the use of a plate that is pre-coated with a proprietary polyubiquitin-capture reagent. The E1 enzyme and ubiquitin are provided in the plate along with twenty-four E2 enzymes. Addition of ATP and of the E3 ligase of interest initiates the polyubiquitination process. The resulting polyubiquitin chains are captured in the wells and are detected in a chemiluminescent “sandwich” ELISA-like assay.
