Application
4-Chloro-7-nitrobenzofurazan (NBD-chloride) is a fluorescence assay reagent used to label free sulfhydryls and N-terminals within proteins. NBD-chloride is used as an enzyme inhibitor and as a trapping agent for cysteine sulfenic acid.

A fluorogenic derivatization method was developed to distinguish the protein N-terminal acetylation status. The unacetylated protein selectively reacted with 4-chloro-7-nitrobenzofurazan (NBD-Cl) at neutral pH to provide high fluorescence. In contrast, the protein with N-terminal acetylation was essentially nonfluorescent under the
