Description

Dansyl-L-Glutamine is a fluorescently labeled derivative of the amino acid L-glutamine, widely used as a critical reagent in biochemical research and analytical chemistry. Its primary value lies in its dansyl fluorophore, which enables highly sensitive detection and quantification in complex biological matrices. This compound is essential for researchers and manufacturers in the pharmaceutical, diagnostic, and life science sectors, particularly for applications involving protein sequencing, amino acid analysis, and fluorescence-based assays.

Application

• Biochemical Research: Used as a fluorescent tracer and derivatization agent in the study of protein structure, function, and metabolism.
• Analytical Chemistry: Serves as a high-sensitivity standard and reagent in High-Performance Liquid Chromatography (HPLC) and capillary electrophoresis for amino acid analysis.
• Pharmaceutical Development: Employed in the research and quality control of peptide-based drugs and other biopharmaceuticals.
• Diagnostic Assays: Acts as a key component in developing fluorescent probes and kits for clinical diagnostics and biomedical testing.
• Neuroscience Studies: Utilized in research investigating glutamatergic signaling and neurotransmitter dynamics due to its specificity for glutamine pathways.
• Process Monitoring: Applied in bioprocessing to monitor cell culture media and fermentation broths for amino acid content.
