Ac-QPKK(Ac)-AMC

Ac-QPKK(Ac)-AMC is a fluorogenic substrate for sirtuin 1 (SIRT1), SIRT2, and SIRT3. It is selectively deacylated by SIRT1-3 over SIRT6. Upon enzymatic cleavage by SIRT1, SIRT2, or SIRT3, 7-amino-4-methylcoumarin (AMC) is released and its fluorescence can be used to quantify SIRT1, SIRT2, and SIRT3 activity. AMC displays excitation/emission maxima of 340-360/440-460 nm, respectively.Formal Name: N2-acetyl-L-glutaminyl-L-prolyl-L-lysyl-N6-acetyl-N-(4-methyl-2-oxo-2H-1-benzopyran-7-yl)-L-lysinamide.
