Beschreibung

General description

This reagent can be used to introduce a hydroxylamine functionality to N-terminal or side-chain amino groups. Hydroxylamine-labeled peptides prepared in this manner can be ligated in aqueous solution at pH 3.5 to aldehyde-containing peptides via oxime formation. This bis-protected derivative eliminates oligomer formation which can occur with mono-protected hydroxylamine reagents as a result of double acylation. Coupling of this derivative should be done using an OSu ester.
