HDAC Substrate

Ac-QPKK(Ac)-AMC acetate is a p53-derived peptide conjugated with a fluorophore, which serves as a fluorescent peptide substrate for detecting the deacylase activity of zinc-dependent HDACs and sirtuins (Ex = 360 nm; Em = 460 nm).

Ac-ETDK(myr)-AMC acetate is a DLAT-derived ε-N-myristoyllysine peptide substrate for fatty-acid deacylase HDAC11, used in fluorescence-based HDAC11 activity assays. Ac-ETDK(myr)-AMC acetate undergoes cleavage of ε-N-myristoyllysine by HDAC11, followed by trypsin-mediated cleavage of C-terminal lysine to release measurable fluorophore AMC.

Ac-QPKK(Ac)-AMC is a p53-derived peptide conjugated with a fluorophore, which serves as a fluorescent peptide substrate for detecting the deacylase activity of zinc-dependent HDACs and sirtuins (Ex = 360 nm; Em = 460 nm).

Z-MAL is a highly efficient and broad-spectrum HDAC substrate. Z-MAL exhibits high conversion activity for class I, II histone deacetylases, and class III SIRT1. Z-MAL can be used in studies on the structure-activity relationship, subtype selectivity, and inhibitor screening of HDAC.
