Properties

Description

Mal-PEG3-NHS ester serves as a PEG linker featuring both a maleimide group and an NHS ester moiety. The hydrophilic nature of its PEG spacer improves solubility in water-based environments. This NHS ester allows for labeling primary amines t-present within proteins or other similar compounds containing amino functionalities, while the maleimide group reacts with thiol groups to create covalent bonds that facilitate connections between biomolecules and thiols.
