Research Use Only

The UbcH7 (Ubiquitin-conjugating enzyme E2 L3 or UBE2L3) TR-FRET Assay Kit is a homogeneous, sensitive TR-FRET assay designed to measure UbcH7 ubiquitination activity in a 384-reaction format. It utilizes biotin-labeled Ubiquitin and a Terbium-labeled antibody recognizing the His-tagged UbcH7 protein to complete the TR-FRET pairing. This FRET-based assay requires no time-consuming washing steps, making it especially suitable for high throughput screening applications. The kit contains enough purified UbcH7 (full-length, His-Tag), purified UBE1, Biotin-Ubiquitin, anti-His Tb-labeled donor, dye-labeled streptavidin acceptor, and assay buffer for 400 reactions. The Terbium-labeled anti-His antibody binds to the His-tagged E2 conjugating protein, while the Dye-labeled streptavidin acceptor binds to Biotinylated-Ubiquitin. The complex forms when ubiquitin is transferred to the E2 enzyme, and the TR-FRET signal can be measured using a fluorescence plate reader capable of measuring Time Resolved-Fluorescence Resonance Energy Transfer.
