We have developed homogeneous, luminescent proteasome assays that are ideal for high throughput screening in 96- and 384-well formats. The Proteasome-Glo™ Assays measure all three catalytic activities of the proteasome using the substrates, Suc-LLVY-aminoluciferin, Z-LRR-aminoluciferin, and Z-nLPnLDaminoluciferin, in a purified enzyme context. The Proteasome-Glo™ Cell-Based Assay measures the chymotrypsin-like activity directly in cells using the substrate, Suc-LLVY-aminoluciferin, and a selective permeabilizing agent.
