Bioassay Systems QuantiFluo™ Pepsin Inhibitor Assay Kit, For evaluation of drugs and screening of potential inhibitors to pepsin proteases.
PEPSIN (EC 3.4.23.1) is a digestive, serine protease that hydrolyzes dietary proteins in many eukaryotic and prokaryotic organisms. Pepsin predominantly cleaves peptide chains at the amino side of the aromatic phenylalanine, tryptophan, and tyrosine amino acids. BioAssay Systems’ QuantiFluo™ Pepsin Inhibitor Assay Kit uses a fluorescein isothiocyanate (FITC)-labeled synthetic substrate. The fluorescein label is highly quenched. Upon digestion by pepsin present in the sample, the substrate is cleaved into smaller peptides, which abolishes the quenching of the fluorescence label. The fluorescence or fluorescence polarization (FP) of the FITC-labeled fragments is measured at λex/em = 485/530 nm. Inhibition is determined by the decrease in fluorescence.
