C-CBL-Driven SRC Ubiquitination Intrachain TR-FRET Assay Kit

The C-CBL-driven SRC Ubiquitination Intrachain TR-FRET Assay Kit utilizes a Europium cryptate-labeled Ubiquitin Donor and a Cy5-labeled Ubiquitin Acceptor to complete the TR-FRET pairing. Since both the TR-FRET donor and acceptor are incorporated into poly-ubiquitin chains, this assay does not detect mono-ubiquitination. The FRET-based format requires no time-consuming washing steps, making it especially suitable for HTS applications as well as real-time analyses of polyubiquitination.
