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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
