Product Keywords: Pharmaceutical Excipients; Other Materials; Methoxy polyethylene glycol-poly(D, L-lactic acid); Carrier Excipients; Carrier Excipients; CH3(C2H4))m(C6H10O2)n. Chemical Name: Methoxy polyethylene glycol-poly(D, L-lactic acid). Grade: Pharmceutical Excipients. Stability and Storage Conditions: MPEG-PLGA is sensitive to light and temperature, for best use, the material should always be kept dry at low temperature and avoid frequent thawing and freezing. MPEG-PLGA should be kept dry at a low temperature below 4°C, protected from light, and the material can be handled under an inert gas for optimal stability. Retest the material after 12 months. Applications: Methoxypolyethylene glycol-polylactic acid (mPEG-PLA) is a block copolymer, one end is a hydrophilic segment - methoxypolyethylene glycol, and the other end is an lipophilic segment - polylactic acid. By adjusting the molecular weight or the ratio of hydrophilic/lipophilic segments, methoxypolyethylene glycol-polylactic acid can be used as a carrier material for different types of drugs, and improve the water solubility, encapsulation efficiency and drug loading of drugs. Methoxypolyethylene glycol-polylactic acid can be made into drug-loaded
Polyethylene glycol (PEG) compounds contain a polyether unit, commonly expressed as R1-(O-CH2-CH2)n-O-R2. They are generally biocompatible, non-toxic and stable in both organic and aqueous solutions, and so are extensively used in biological applications, as well as nanotechnology and materials research. Proteins with PEG chain modifications and compounds encapsulated in PEG liposomes exhibit a longer half-life in vivo than their non-PEGylated counterparts, a phenomenon known as PEG shielding. Functionalised PEG lipids and phospholipids can be used for protein-PEG conjugation. Uses: Activated peg derivatives can be used to modify peptides, proteins, or in other bioconjugation applications. pegylated materials have found broad use in drug delivery systems, virology, and immunology, as the incorporation of peg improves pharmacological properties such as increased water solubility, enhanced resistance to degradation (protein hydrolysis), increased circulation half-life, and reduced antigenicity. in addition to pegylation, activated peg derivatives can also be used to form networks for tissue engineering or drug delivery applications, depending on the architecture and reactivity.
