Application

Fluram (fluorescamine) is a non-fluorescent reagent that reacts readily under mild conditions with primary amines in amino acids and peptides and other molecules to form stable, highly fluorescent compounds. Fluorescamine is useful for the fluorometric assay of amino acids, protein, and proteolytic enzymes and as a pre-column derivatization reagent. It effectively blocks newly generated amino termini in protein sequence analyses.
Non-fluorescent reagent that reacts readily under mild conditions with primary amines in amino acids and peptides to form stable, highly fluorescent compounds. Low background due to hydrolysis. Useful for the fluorometric assay of amino acids, protein, and proteolytic enzymes. Effectively blocks newly generated amino termini in protein sequence analyses.
