20S Constitutive Proteasome Assay Kit

South Bay Bio's kit is designed to test for specific activity of 20S proteasome. The kit provides purified 20S proteasome and is designed to test for Chymotrypsin-like activity (Suc-LLVY-AMC), Caspase-like activity of the proteasome subunits beta1/PSMB6 (LLE-AMC) and Chymotrypsin-like activity of beta5/PSMB5 (WLA-AMC). Additionally, the compound MG-132 is included, which can be used to inhibit the proteasome. All peptide substrates are conjugated to AMC, which upon proteasome catalyzed hydrolyses display fluorescence at Excitation=345nm, Emission=445nm; allowing for a real-time read out of 20S proteasome specific activity.
