Lipoic acid PEG azide, LA-PEG-N3

Description:

Lipoic acid PEG azide is one of Nanocs’ surface reactive PEG derivatives that have a lipoic acid moiety on one PEG terminus and an azide group on the other PEG end. Lipoic acid, also known as thioctic acid, is an important bioactive molecule participating in various biological processes. PEG functionalized lipoic acid can be used to bind to metallic particle or film surface with its disulfide bond. Lipoic acid group has high affinity to metallic surfaces and have been widely used for gold nanoparticles and quantum dots surface modification. Azide group can react with linear alkye or strain-promoted cyclooctyne through so called Click Chemistry. PEGylated lipoic acid azide is water soluble and can be used directly in aqueous buffer.
