Fluorescamine is widely used in biochemistry and molecular biology for the detection and quantification of primary amines, such as amino acids, peptides, and proteins. It reacts with these compounds to form highly fluorescent products, making it a valuable tool in analytical techniques like high-performance liquid chromatography (HPLC) and fluorescence spectroscopy. This property allows researchers to monitor enzymatic reactions, study protein structures, and analyze amino acid composition with high sensitivity. Additionally, it is utilized in labeling biomolecules for imaging and diagnostic purposes, aiding in the study of cellular processes and disease mechanisms. Its ability to provide rapid and specific detection makes it essential in both research and clinical laboratories.
