| 产品介绍 | Fluoraldehyde OPA Reagent is a ready-to-use solution of o-phthalaldehyde, a fluorescent derivatization reagent for peptide or amino acid detection and quantitation in HPLC. Fluoraldehyde Reagent Solution contains OPA (o-phthalaldehyde), which reacts with primary amines of amino acids, peptide and proteins to enable fluorescent detection and quantitation. The reagent that can be used as a protein or peptide assay reagent or as a pre- or post-column detection reagent for amino acid analysis (HPLC). Reaction of OPA with proteins and peptides yields linear results over a wide range of concentrations. The Fluoraldehyde Reagent Solution is supplied ready to use and enables fast quantitation of proteins or peptides in solution. Highlights: ?For pre- or post-column amino acid derivatization for fluorescent detection and quantitation ?Reacts with all primary amine-containing analytes to yield fluorescent isoindole derivatives ?Provides an accurate measure of both composition and absolute protein-peptide content ?Ideal for work with recombinant proteins and synthetic peptides ?Can be used for fluorescent protein or peptide assay ?Pre-column derivatization mixtures can be injected into LC without any processing |
