Description

Dansyl-ε-Aminocaproic Acid is a specialized fluorescent labeling reagent that combines the dansyl fluorophore with an aminocaproic acid spacer arm. This compound is critical for the derivatization and sensitive detection of amines, amino acids, and other primary amine-containing biomolecules in analytical chemistry. It is primarily utilized by researchers and quality control laboratories in the pharmaceutical, biotechnology, and life science sectors for high-performance liquid chromatography (HPLC) and capillary electrophoresis applications.

Application

• Pre-column derivatization agent for the HPLC analysis of amino acids, peptides, and biogenic amines to enhance detection sensitivity and selectivity.
• Fluorescent probe synthesis for labeling proteins, antibodies, and other biomolecules to study protein interactions, localization, and dynamics.
• Biomarker detection and assay development in clinical diagnostics and pharmaceutical research for quantifying low-abundance analytes.
• Quality control testing in pharmaceutical manufacturing for the analysis of drug substances and products containing primary amine functional groups.
• Proteomics and metabolomics research, facilitating the separation, identification, and quantification of complex biological samples.
• Chemical biology tool for creating fluorescent conjugates used in cellular imaging and flow cytometry.
