Methyltetrazine-PEG12-amine HCl Salt
This product is a heterobifunctional linker with a methyltetrazine group, a PEG12 spacer, and a terminal amine provided as a hydrochloride salt. The methyltetrazine reacts ultrafast with trans-cyclooctene (TCO) specifically through copper-free IEDDA ligation. The amine couples efficiently with carboxyls or activated esters, while the PEG12 chain improves solubility, flexibility, and spacing, making this reagent highly versatile for bioconjugation and drug delivery.
