Specifications

The E1 LITE – UBE1 Activity Assay is a kit for assessing E1 enzyme activity. This plate-based assay is based on the transfer of FRET energy between the acceptor-charged ubiquitin and the donor-charged ubiquitin as they both bind to the E1 enzyme. The assay employs terbium as the donor fluorophore, which has a long-lived fluorescence allowing for a time-delayed reading of the FRET signal, or time-resolved FRET (TR-FRET). This reduces the contribution from buffers, proteins, and chemical compounds.
