MONO-METHYL POLYETHYLENE GLYCOL 5'000 2-MALEIMIDOETHYL ETHER Chemical Properties,Usage,Production

Uses

for immobilization, water insoluble version of 7-00246

Uses

Methoxypolyethylene glycol maleimide (MeO-PEG-Mal) is used as a protein pegylation reagent. PEGylation is the process of covalently attaching polyethylene glycol (PEG) polymer chains to other molecule such as proteins.

Uses

Poly(ethylene glycol) methyl ether maleimide is a maleimide-functionalized poly(ethylene glycol). Due to the maleimide-functionalization, this material can be used to rapidly conjugate thiol-containing biomolecules, APIs, or targeting ligands.

reaction suitability

reagent type: chemical modification reagent
reactivity: thiol reactive
