Thermo Scientific™ MT(PEG)4 Methyl-PEG-Thiol Compound
Shop All Thermo Scientific ProductsDescription
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.
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
