Description:

Lipoic acid PEG Biotin is one of Nanocs's surface reactive PEG derivatives that has a lipoic acid on one end of PEG chain and a biotin tag 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 -S-S-bond. Lipoic acid group has high affinity to metallic surfaces and have been widely used for gold nanoparticles and quantum dots surfaces. PEGylated lipoic acid is water soluble and can be used directly in aqueous buffer.

Physical Properties:

• Form: Solid or viscous liquid depends on molecule weight;
• Color: Light yellow to yellow;
• Functional groups: Lipoic acid and biotin;
• Binding targets: Metal surfaces and streptavidin/avidin;
• Solubility: Soluble in regular aqeous solution, ethanol and most organic solvents;

Storage Conditions:

• Store at 4 ⁰C or lower, Dessiccate. Protect from light. Avoid frequent thaw and freeze.
