Description

Quantity: 100 mg
Unit Size: Each
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
