Description
OverviewA fluorogenic FRET peptide with a substrate sequence that is optimized for calpain-1 and -2 (Cat. Nos. 208712, 208713, 208715, and 208718) based on 106 known cleavage sites. It is cleaved by mammalian calpains with a much better efficacy (kcat/Kmx10-2 (M-1s-1) = 69.8, 38.5, 20.0, 6.81, 3.58, 0.05, and < 0.05 for calpain-2, trypsin, papain, calpain-B, calpain-A, chymotrypsin, and cathepsin-B, respectively) and kinetically superior to other commonly used calpain substrates, such as LY-AMC (Cat. No. 208731) and α-spectrin cleavage site-based substrate (Cat. No. 208748). Has been used successfully in monitoring calpain activity in whole Drosophila S2 cells (cellular incorporation achieved with a lipofection reagent) and in COS-7 cell lysate.
