Monomethoxyl Poly Ethylene Glycol B L Lactide - China

price: contact company for price

Name: Monomethoxyl poly(ethylene glycol)-b-poly(L-lactide)

Product Model : mPEG-PL

Chemical Formula : CH3(C2H4O)m (C6H8O4)n

Chemical Structure :

Instructions : Monomethoxyl poly(ethylene glycol)-b-poly(L-

lactide) mPEG-PLA is a block copolymer. One block is

hydrophilic monomethoxyl poly(ethylene glycol), the other

block is lipophilic poly(L-lactide). mPEG-PLA can be used as

the carrier material of different types of drugs to improve

the water solubility of drugs, encapsulation efficiency and

drug loading rate.

mPEG-PLA can find usage in microspheres, microcapsules,

vesicles, micelles, sustained release of drugs, controlled

release, tissue engineering scaffolds, etc.
