Tetrazine PEG

Tetrazine-PEG combines a tetrazine group with a PEG chain for fast and efficient bioorthogonal click chemistry. It reacts rapidly with TCO or other strained alkenes, even at low concentrations. The PEG chain boosts solubility and reduces immune responses. Ideal for bioconjugation, drug delivery, and live-cell labeling, it offers precise and quick biomolecule modification in aqueous environments.
