PEG Linkers


Poly(ethylene glycol) (PEG) is a synthetic, hydrophilic, biocompatible polymer with widespread use in biomedical and other applications. PEGs are synthesized using a ring-opening polymerization of ethylene oxide to produce a broad range of molecular weights and molecular weight distributions (polydispersity). PEGs can be synthesized in linear, branched, Y-shaped, or multi-arm geometries. PEGs can be activated by the replacement of the terminal hydroxyl end group with a variety of reactive functional end groups enabling crosslinking and conjugation chemistries. AA Blocks offers a comprehensive list of high purity PEGylation products to empower your PEGylation, bioconjugation, crosslinking, ADC drug development, biolabeling for pharmaceutical and biotech R&D.
