PR1101: Ub-CHOP2 Reporter System


In stock

SKU: PR-1101-0375 Category:


The Ub-CHOP2-Reporter Deubiquitylation Assay consists of ubiquitin fused to a reporter enzyme, as well as a separate reagent substrate for the reporter enzyme. When fused to ubiquitin, the reporter is rendered catalytically inactive. Following cleavage of the Ub-reporter system by the isopeptidase, the free (and now active) reporter subsequently acts upon its substrate. Thus, in this coupled assay, the signal generated by cleavage of the reporter enzyme’s substrate is a quantitative measure of isopeptidase activity.
