PTDA-PEG4-Azide is composed of a PTAD moiety and an azide. The PTAD moiety is used for the tyrosine click reaction, and the azide is used for the heterobifunctional linker of click chemistry.
PTDA-PEG4-Azide is a type of water-soluble polymer. It is a poly(2,2,6,6-tetramethylpiperidinyloxy-4-methyl-1,4-phenylene) (PTDA) chain with four poly(ethylene glycol) (PEG) side-chains terminated with an azide group. The azide group allows for further conjugation of a variety of molecules, such as antibodies, enzymes, and fluorescent probes.
