A highly selective and facile assay of human immunodeficiency virus protease (HIV-PR) has been required for the screening of medicinal inhibitors and also for classifying the subtypes of HIV in the therapeutic treatment of acquired immune deficiency syndrome (AIDS). This article describes a novel assay method of HIV-PR based on the selective fluorogenic reaction of peptides. A peptide fragment generated...
A novel and selective fluorescence reaction is proposed for the quantitative determination of peptides by reversed-phase liquid chromatography (RPLC). A single fluorescent product was formed when a peptide was heated at 120°C for 20min in a neutral aqueous medium (pH 7.0) containing catechol, sodium periodate, and sodium borate. The fluorescent products of four peptides such as Leu-Gly, Ala-Leu-Gly,...
