Description:

mPEG-LA  is one of Ponsure bioactive and surface active PEG derivatives that contain a lipoic acid linked to a linear PEG chain. Lipoic acid, also known as thioctic acid, is an important molecule participating in various biological processes. It is also a good metal chelator. PEG chain linked to lipoic acid offers good water solubility, flexible linker structure and enhanced biocompatibility. Ponsure lipoic acid functionalized polyethylene glycol (LA-PEG) is readily soluble in water and it can be used for many biomedical applications. With its good binding affinity to gold metal, this item can also be used for gold nanoparticle surface modification.

Handling and Use:

mPEG-LA  is sensitive to light and temperature. For best use, material should always be kept in low temperature in dry condition.

 Avoid frequent thaw and freezing. For more information about using this product, visit www.ponsure.com.

Storage Conditions：

mPEG-LA should be stored at -20℃. Desiccate.  Materials may be handled under inert gas for best stability. Re-test material after 12 months.
