Methyltetrazine-NHS Ester is a NHS actived building block containing a methyltetrazine group. It can react with primary amines such as the side chain of lysine residues or aminosilane-coated surfaces at neutral or slightly basic pH to form covalent bonds. Methyltetrazine enable fast click reaction with TCO (trans-cycloctene).
Methyltetrazine-NHS ester has an N-hydroxysuccinimide (NHS) ester that can be reacted with primary amines and a methyltetrazine, which is reactive to trans-cyclooctenes. The NHS ester reacts with primary amines (e.g. side chain of lysine residues or aminosilane-coated surfaces) at neutral or slightly basic pH to form covalent bonds. The short spacer arm adds minimal mass to modified molecules (230.2 daltons). It is generally used in click chemistry applications in bioconjugate chemistry.
