PEG Linkers

​​PEG linkers are chemically functionalized polyethylene glycol linkers that can be attached to molecules, most typically peptides, proteins, and antibody fragments. PEG linkers have attracted considerable interest and are widely used in biological and medical research due to their solubility in water, excellent biocompatibility, and non-immunogenicity. PEG linkers have had a significant impact on medical research with the ability to prolong the circulation half-life, improve solubility and reduce protease sensitivity of the drug. In addition, biomolecules modified with PEG linkers show enhanced resistance to degradation in organisms, better pharmacokinetics, and the ability to cross the blood-brain barrier.
