Application: Human pro-neuropeptide Y (34–43) FRET Substrate is a synthetic peptide fragment containing a cathepsin cleavage site involved in neuropeptide processing. Host proteases such as cathepsin L participate in neuropeptide biosynthesis and can also contribute to viral protein activation during cell entry. Labeled with QXL®520 and 5-FAM as a FRET pair, this peptide functions as a sensitive enzymatic substrate for protease cleavage assays. It is useful for studying cathepsin activity, neuroendocrine regulation, protease kinetics, host–virus proteolytic interactions, and inhibitor screening in biochemical assay systems.
