General description

A reagent for the reversible labeling of peptides with biotin [1]. Labeling of the N-terminal amine of resin-bound peptides is carried out by incubating overnight with excess reagent in DMF. The biotinylated peptide is obtained following TFA cleavage. Removal of the biotin label is effected by treatment with 5% aqueous hydrazine.
