Tetrazine-PEG5-NHS ester Structural

What is Tetrazine-PEG5-NHS ester?

Description

Tetrazine-PEG5-NHS Ester is a PEG linker containing a tetrazine group and an NHS ester which is very reactive with amine(NH2)-containing molecule. Methyltetrazine enable fast click reaction with TCO (trans-cycloctene).

The Uses of Tetrazine-PEG5-NHS ester

Tetrazine-PEG5-NHS ester (Tz-PEG5-NHS) can be used in click chemistry applications such as the preparation of chitosan-polyacrylamide microspheres utilizing selective tetrazine-trans-cyclooctene (Tz-TCO) ligation and the construction of copper-64 radiolabeled antibody by the click reaction.

General Description

Tetrazine-PEG5-NHS ester has an N-hydroxysuccinimide (NHS) ester that can be reacted with primary amines and tetrazine, which is reactive to trans-cyclooctenes. Hydrogen substituted tetrazines demonstrate exceptionally fast kinetics, generally at least 10-fold faster compared to methyl substituted tetrazines. The aqueous solubility of this reagent is substantially enhanced by a hydrophilic polyethylene glycol (PEG) spacer arm.
