alpha-MaleiMidopropionyl-oMega-succiniMidyl-8(ethylene glycol) Chemical Properties,Usage,Production

Description

Mal-amido-PEG8-NHS is a PEG linker containing a maleimide group and an NHS ester. 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.

Uses

Heterobifunctional crosslinker with an ethylene oxide spacer for linking amine- to sulfhydryl-containing compounds or biomolecules. Maleimide functional group will react with sulfhydryls and the succinimidyl ester group will react with amines. Spacer length is 39.2 angstroms.
