Methyltetrazine-PEG4-NHS ester,1802907-92-1

应用

Methyltetrazine-PEG4-NHS ester is a crosslinker with enhanced stability and water solubility. This crosslinker has an NHS ester that can be reacted with a primary amine and a methyltetrazine that is reactive with trans-cyclooctenes. Methyltetrazine-PEG4-NHS ester is one of the most stable tetrazines commercially available. In addition to stabilization provided by the electron donating methyl group, the electron donating alkoxy substituent on the aromatic ring further improves the stability of methyltetrazine-PEG4-NHS ester. The aqueous solubility of this reagent is substantially enhanced by a hydrophilic polyethylene glycol (PEG) spacer arm.
