Protein polyglycolization September 3,2020.

The coupling of PEG to protein is also called protein polyglycolization, which is essentially a drug delivery technology. The coupling of activated peg with protein molecules can improve the three-dimensional space state of proteins, resulting in changes in various biochemical properties of proteins. For example, chemical stability increased, half-life prolonged, immunogenicity and toxicity decreased or disappeared, protein solubility increased. SINOPEG is a dynamic science company dedicated to drug delivery systems (DDS). SINOPEG are specialized in the R&D of long acting biopharmaceuticals, developing and manufacturing of block copolymers, lipids for drug delivery, medical devices, bio-engineering, and other broad uses.


Up to now, the FDA has approved 20 polyglycolic drugs. In addition to monoclonal antibodies, polyglycolic drugs have become the most powerful drug development technology.As a leading company in polyethylene glycol derivatives (PEGs), SINOPEG is capable of supplying small to large quantities of rich selection of PEG derivative products with unique molecular designs (chemical structure, molecular weights (MW)) and exceptional product quality control to serve bio-technology and pharmaceutical companies and research organizations worldwide.
