Methyltetrazine-PEG-Biotin

Methyltetrazine-PEG-Biotin combines a methyltetrazine group for rapid bioorthogonal click chemistry with a biotin moiety for high-affinity streptavidin binding. The PEG spacer in Methyltetrazine-PEG-Biotin enhances aqueous solubility and reduces steric interference during target engagement. Methyltetrazine-PEG-Biotin is particularly suitable for pre targeted imaging, pull-down assays, and affinity-based detection systems requiring fast kinetics and robust capture.
