BPS BioscienceReady-to-use 96-well fluorometric assay kit for measuring SARS-CoV-2 3CL protease activity. Ideal for screening inhibitors and studying enzyme kinetics in high-throughput applications.
The 3CL Protease Assay Kit is designed to measure 3CL Protease activity for screening and profiling applications, in a homogeneous assay with no time-consuming washing steps. The kit comes in a convenient 96-well format, with purified 3CL Protease MBP-tag (BPS Bioscience #100707), fluorogenic substrate, and 3CL Protease assay buffer for 100 enzyme reactions.
3CL inhibitor GC376 is also included as control. The 3CL Protease Substrate is an internally quenched 14-mer fluorogenic (FRET) peptide (DABCYL-KTSAVLQSGFRKME-EDANS).
When the donor (EDANS) and acceptor (DABCYL) fluorophores are in close proximity, the energy emitted from EDANS is quenched by DABCYL (intact substrate).
Upon proteolysis by 3CL, the peptide substrate is cleaved between glutamine and serine by the 3CL protease to generate the highly fluorescent peptide fragment (SGFRKME-EDANS). The fluorescence intensity increases proportionally to the activity of 3CL.
More information on the substrate, including MW and structure, can be found on our website (BPS Bioscience #79952).
