Application

This heterobifunctional, PEGylated crosslinker features a carboxylic acid at one end and propargyl group at the other for reaction with azide-containing compounds using click chemistry. The hydrophilic PEG linker facilitates solubility in biological applications. Propargyl-PEG6-acid can be used for bioconjugation or as a building block for synthesis of small molecules, conjugates of small molecules and/or biomolecules, or other tool compounds for chemical biology and medicinal chemistry that require ligation. Examples of applications include its synthetic incorporation into antibody-drug conjugates or proteolysis-targeting chimeras (PROTAC® molecules) for targeted protein degradation.
