We develop a label-free and high-throughput bioluminescence method for the sensitive detection of uracil DNA glycosylase (UDG) through enzyme-mediated tricyclic cascade signal amplification. This method exhibits high sensitivity with a detection limit as low as 0.00031 U mL(-1), and it can be further applied for the measurement of enzyme kinetic parameters and the screening of UDG inhibitors as well as cancer cell analysis.
