Boc-LRR-AMC is a fluorescent substrate for Trypsin, similar to the 20S proteasome. Boc-LRR-AMC can be used to detect Trypsin-like activity in the 26S proteasome or 20S proteasome core. The detection wavelength of Boc-LRR-AMC is 380nm/460nm[1].

1. Antibody coating: Prepare 5μg/ml of the target antibody to coat a black 96-well maxisorp plate, which is then further blocked for 1 hour using PBS containing 2% BSA.
2. Proteasome capture: Cell pellets were washed in PBS and lysed on ice at a cell density of 107 cells/ml in lysis buffer (50mM TRIS, 0.1% NP40, pH 7.5). The supernatant was collected, analyzed using the BCA protein assay reagent, and the protein content was adjusted to a concentration of 200μg/ml in lysis buffer. 50μl of cell lysate was then added to each well, and the plate was incubated at 4°C for 2 hours. The amount of proteasomes captured under these conditions was adjusted to approximately 200ng per well using a quantitative ELISA assay [3].
3. Substrate incubation: After capturing the proteasomes, the plates were first carefully washed with 20mM Tris buffer (containing 0.1% NP40, pH 7.5) and then washed with 20mM Tris buffer (pH 7.5) to remove excess material. Proteasome inhibitors diluted in 20mM Tris buffer (pH 7.5) were then added to the wells and incubated with rotation at room temperature for 10 minutes. Finally, the fluorescent substrate Boc-LRR-AMC was diluted in 20mM Tris buffer and added to the wells at a concentration of 100μM.
4. Fluorescence detection: The plates were sealed with a plastic cover and incubated at 37°C for approximately 30 minutes. Fluorescence values were then measured using a Proteasome-GloMAX or SpectraMax 190 microplate reader at an excitation wavelength of 380nm and an emission wavelength of 460nm.

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
