Boc-LRR-AMC is a fluorogenic substrate for the trypsin-like activity of the 26S proteasome or 20S proteolytic core. Upon enzymatic cleavage by the 26S proteasome or 20S proteolytic core, amino-4-methylcoumarin (AMC) is released and its fluorescence can be used to quantify 26S proteasome or 20S proteolytic core trypsin-like activity. AMC displays excitation/emission maxima of 340-360/440-460 nm, respectively.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
