General description
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.†
