Fluorescamine is widely used in biochemistry and molecular biology for the detection and quantification of primary amines, particularly in proteins and peptides. It reacts with primary amines to form highly fluorescent products, making it a valuable tool for labeling and tracing these compounds in various analytical techniques. This property is especially useful in high-performance liquid chromatography (HPLC) and gel electrophoresis, where it helps in visualizing and quantifying amino acids, peptides, and proteins. Additionally, it is employed in the study of enzyme kinetics and protein sequencing, providing insights into the structure and function of biomolecules. Its sensitivity and specificity make it a preferred choice for research involving low-concentration amine-containing compounds.
