Mal-PEG6-NHS ester 是一种不可降解的 ADC linker，含有 Maleimide 基团，6 单元 PEG 和 NHS 酯 Mal-PEG6-NHS ester is a PEG derivative containing a maleimide group and an NHS ester group. The hydrophilic PEG spacer increases solubility in aqueous media. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. Mal-PEG6-NHS ester is a nonclaevable ADC linker containing a Maleimide group, 6-unit PEG and a NHS ester. Application： Applicated in medical research, drug-release, nanotechnology and new materials research, cell culture. In the study of ligand, polypeptide synthesis support, a graft polymer compounds, new materials, and polyethylene glycol-modified functional coatings and other aspects of the active compound.
