- Description
Mal-PEG3-COOH is a PEG linker bearing maleimide and terminal carboxylic acid groups. Its hydrophilic PEG spacer supports aqueous solubility. The maleimide terminus reacts with thiols to form stable covalent linkages, while the carboxylic acid can be coupled to primary amines using activators such as EDC or HATU to form amide bonds. These complementary functional groups enable bioconjugation involving thiol- and amine-containing biomolecules. The listed purity is ≥95%.
