Amino-PEG9-acid（Cat No.:I014117） is a linker molecule that is commonly used in the synthesis of Proteolysis Targeting Chimeras (PROTACs) and antibody-drug conjugates (ADCs). It belongs to the PEG class of compounds and acts as a bridge to connect the target protein-binding ligand and the drug molecule. Amino-PEG9-acid is a non-cleavable linker, meaning that it forms a stable bond between the antibody and the drug payload in ADCs. This linker offers stability to the conjugate during circulation and helps to enhance the therapeutic efficacy of the ADC in targeted therapy approaches.
