Description
Methyltetrazine-PEG8-PFP ester is an PFP active building block containing a methyltetrazine group. This compound can react with 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. The hydrophilic PEG spacer increases the hydrophilic properties of the compound
