Azido-PEG4-Ala-Ala-Asn(Trt)-PAB produced by AXISPHARM is a PEG derivative conjugated to a peptide via an amide bond. For antibody-drug conjugation, the azide group is highly reactive towards DBCO, BCN or other alkynyl groups, and the azide group at the PEG end makes Click Chemistry possible. Hydrophilic PEG spacers increase solubility in aqueous media.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
