Description

Description générale

1-Fluoro-2,4-dinitrobenzene (DNFB) is a reagent that modifies the N-terminal amino acids of proteins and peptides. DNFB is also commonly known as Sanger′s Reagent, named after Frederick Sanger, who reported in a classic 1945 paper the use of DNFB for derivatization of proteins and peptides specifically at their N-termini.†

Application

1-Fluoro-2,4-dinitrobenzene has been used to induce severe contact hypersensitivity in mice and to monitor gene expression by in vivo imaging method, and to induce chronic itch as a model for analysing itch-scratching behavior.

Actions biochimiques/physiologiques

1-Fluoro-2,4-dinitrobenzene is a contact-sensitizing hapten, commonly used in experimental studies on contact hypersensitivity, inducing itch model, and atopic dermatitis. Mast cell activation is a key step in the DNFB induced sensitivity. DNFB covalently binds to the N-terminal amino acid of the protein and aids in Sanger sequencing.
