The lipoic acid moiety forms dative bonds with gold, silver, and other metals and can be used to coat or passivate metal surfaces. The maleimide group forms stable thioether bonds with free thiols and can be used to immobilize a sulfhydryl-containing biomolecule such as a peptide or antibody fragment to a metal surface through the dPEG®-lipoamide linkage. The flexible, non-immunogenic, hydrophilic dPEG® linker adds water solubility and increases the conjugate's hydrodynamic volume.

Specifications

Unit Size 100mg, 1000mg
Molecular Weight 884.11; single compound
Chemical formula C₃₉H₆₉N₃O₁₅S₂
CAS 1334172-73-4
Purity > 97%
Spacers dPEG® Spacer is 49 atoms and 59.3 Å
Shipping Ambient
Typical solubility properties (for additional information contact Customer Support) Methylene chloride, DMAC or DMSO.
Storage and handling -20°C; Always let come to room temperature before opening; be careful to limit exposure to moisture and restore under an inert atmosphere; stock solutions can be prepared with dry solvent and kept for several days (freeze when not in use). dPEG® pegylation compounds are generally hygroscopic and should be treated as such. This will be less noticeable with liquids, but the solids will become tacky and difficult to manipulate, if care is not taken to minimize air exposure.
