Figure 1. Proteasome activity in living cells. HEK 293 cells stably transfected with the Proteasome Sensor Vector were selected in G418 and sorted by flow cytometry, and then treated with 10 ¥ìM ALLN for the indicated times. ALLN is a peptide aldehyde (Ac-Leu-Leu-Nle-al) that reversibly inhibits the proteasome¡¯s chymotrypsin activity, preventing it from attacking the ZsProSensor-1 protein. As a result, ZsProSensor-1 quickly accumulates, resulting in a strong green emission signal that can be measured by fluorescence microscopy (Panel A), flow cytometry (Panel B), or fluorometry with a 96-well plate reader with FITC filter sets (Panel C).
