Z-Phe-Arg-AFC is a fluorogenic for Cathepsin L. Cathepsin L is a lysosomal cysteine protease with an important role in initiating protein degradation. Cathepsin L is also upregulated in several cancers and has been suggested as a drug target. In addition,  extracellular secretion of Cathepsin L by tumors implicates it as a potential serum biomarker for  cancer progression.

Activity is quantified by release of free fluorescent 7-amino-4-trifluoromethylcoumarin (AFC) which excites at 395-400 nm and emits at 495-505 nm.
