Properties

Description

Mal-PEG4-trimethylammonium chloride is a PEG linker featuring a maleimide group and a quaternary ammonium moiety. The maleimide group selectively reacts with thiol groups to form stable covalent bonds, while the trimethylammonium group imparts a permanent positive charge. The PEG4 spacer enhances hydrophilicity and solubility in aqueous media.
