Description

(n-Dansyl)Biocytinamidoethyl Methanethiosulfonate is a specialized, bifunctional chemical probe designed for site-specific labeling and detection in advanced biochemical research. This compound matters because it uniquely combines a dansyl fluorophore for sensitive detection with a methanethiosulfonate group for selective covalent attachment to cysteine residues, enabling precise protein and peptide analysis. It is primarily needed by researchers and manufacturers in the fields of proteomics, bioconjugation, and diagnostic assay development who require high-purity, reliable reagents for fluorescence-based studies and labeling applications.

Application

• Site-Specific Protein Labeling: Covalent attachment to cysteine residues for fluorescence tagging and structural studies.
• Proteomics Research: Used as a fluorescent probe in gel electrophoresis, blotting, and protein interaction analysis.
• Bioconjugation Chemistry: A key reagent for creating fluorescently labeled antibodies, peptides, and other biomolecules.
• Diagnostic Assay Development: Employed in the synthesis of fluorescent tracers and detection reagents for immunoassays.
• Membrane Protein Studies: Useful for labeling and tracking membrane-associated proteins due to its biocytin-derived moiety.
• Fluorescence Microscopy: Provides a dansyl-based fluorescent tag for cellular and subcellular imaging applications.
• Kinetic and Binding Studies: Enables real-time monitoring of biomolecular interactions through fluorescence changes.
