Thermo Scientific™ MT(PEG)4 Methyl-PEG-Thiol Compound

Description

• Thermo Scientific™ Pierce MT(PEG)4, or methyl-PEG4-thiol, is a methyl- and sulfhydryl-terminated compound that contains a 4-unit polyethylene glycol (PEG) spacer and is used to modify surfaces such as quantum dots, monolayers and magnetic particles
• MT(PEG)4 is monodentate thiol-terminated and methyl pegylation reagent
• The PEG compound has a defined molecular weight and spacer length and is useful for modifying surfaces such quantum dots, self-assembled monolayers and magnetic particles
• Functionalization of solid surfaces with polyethylene glycol spacers such as this one significantly reduces nonspecific protein binding
• Highlights: Metal-binding – terminal monodentate thiol reacts spontaneously with gold surfaces through dative binding Methyl – terminal methyl group is unreactive, the primary function of this compound being to coat quantum dot and other surfaces to reduce nonspecific binding in assays Polyethylene glycol – PEG groups are flexible, non-immunogenic, hydrophilic, and significantly reduce nonspecific binding of surfaces for protein methods Spacer arm – four-unit PEG spacer makes compound nearly 16 angstroms long Specifications: Alternative name: Methyl-PEG4-Thiol Chemical name: 2,5,8,11-tetraoxatridecane-13-thiol Chemical formula: C9H20O4S Molecular weight: 224.32 Spacer arm: 15.8 angstroms Form: clear colorless to light yellow liquid Solubility: dissolve in DMSO or DMF for use
