Azido-PEG1-acid is a non-cleavable heterobifunctional PEG linker containing an azide group and a carboxylic acid. Azido groups react with terminal alkyne and cyclooctyne derivatives by click chemistry, and carboxylic acids can react with amino groups in the presence of activators, which can be used to synthesize antibody-drug conjugates (ADCs).
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
