Description
UbiQ-050 is an activity-based probe for deubiquitinating enzymes (DUBs). It is based on ubiquitin functionalised with a C-terminal electrophilic vinyl methyl ester (VME) and N-terminal 5-carboxytetramethylrhodamine dye. It can be used for activity profiling experiments and the control of DUB inhibitor specificity. Whereas the first-generation activity-based probes (such as HA tagged Ub-VME) require immunoblotting for detection, the second-generation TAMRA-Ub-VME probe allows detection of DUB labeling by in-gel fluorescence.
This direct and more sensitive read-out gives more distinct labeling patterns than can be achieved by immunoblotting. In addition, cross-reactivity of antibodies can lead to background labeling, something that is not observed with TAMRA-Ub-VME.
