Description

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. To induce chronic itch model for analysing itch-scratching behavior.

Packaging

10, 25, 100 mL in glass bottle

Biochem/physiol Actions

1-Fluoro-2,4-dinitrobenzene (DNFB) 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.
