TETA (1,4,8,11-Tetraazacyclotetradecane-1,4,8,11-tetraacetic acid) is a complexing agent for di- and trivalent metal ions. TETA-PEG4-azide is a bifunctional linker containing chelating and azide groups for conjugation with alkyne-containing biomolecules. The structure of the reagent features a long hydrophilic PEG4 linker that separates the TETA residue from the target molecule. The linker also enhances aqueous solubility to facilitate conjugation.
