DBCO-PEG9-DBCO is a click chemistry linker with two DBCO groups and a hydrophilic PEG spacer arm. DBCO is reactive with azide-bearing compounds or biomolecules to form a stable triazole linkage without copper catalyst. The hydrophilic PEG9 arm increase water solubility and membrane permability. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Methyltetrazine-amido-PEG5-alkyne is a heterobifunctional crosslinker. This reagent enables simple and efficient incorporation of a tetrazine moiety onto TCO-attached antibodies, peptide or other biomolecule under mild condition. The alkynes is reactive with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry. PEG5 space increase the compound's aqueous solubility. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Methyltetrazine-PEG8-PFP ester is an PFP containing click chemistry reagent consisting of a methyltetrazine group. NHS ester is reactivewith primary amines such as the side chain of lysine residue or aminosilane-coated surfaces at neutral or slightly basic pH to form covalent bonds. Thus, this reagent can be used for modification of amine-containing molecules in organic media and the low mass weight will add minimal spacer to modified molecules. Methyltetrazine is reaactive with TCO via click chemistry. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
