Custom PEG Solutions for Complex Therapeutics
Gannet BioChem leverages more than 30 years of history as a leader in polyethylene glycol (PEG) reagents
Improve the performance of your drug substance with PEGylation
PEGylation has proven over time that it can improve how drugs work. It can be used in many different ways, including with biologics, small molecules, peptides, and lipid nanoparticles (LNPs). Today, there are more than 80 FDA-approved PEGylated drugs. Because of this success, the need for dependable and new PEG reagents keeps growing.
What is PEGylation?
PEGylation is like giving a medicine a raincoat. The “raincoat” is made of a special material called PEG (polyethylene glycol). When a drug wears this coat, it’s better protected inside the body. That protection helps the medicine last longer, spread more evenly, and sometimes cause fewer side effects. That’s why scientists use PEGylation in lots of medicines, including some cancer treatments.
