Biotin-PEG4-Methyltetrazine

Description

Biotin-PEG4-methyltetrazine is a click chemistry biotinylation reagent that can react with TCO-containing compounds to form a stable covalent bond without the catalysis of Cu or elevated temperatures. The inverse-electron demand Diels-Alder cycloaddition reaction of TCO with tetrazines is the fastest bioorthogonal reaction with exceptional selectivity.
