Polyethylene Glycol Building Blocks for PEGylation

Circulatory half-life is a key success factor for new drugs. In this respect, PEGylation or PEG-ing—the modification of potential candidates ranging from non-peptidic small molecules to peptides and proteins, antibody fragments, aptamers, and saccharides or oligonucleotides with polyethylene glycol chains—offers numerous advantages.
