What are PEG Linkers?

Polyethylene glycol or PEG-linkers are particularly attractive as a linker for conjugation due to their water solubility, lack of toxicity and low immunogenicity. PEG linkers have been widely used in pharmaceutical and biotech applications such as protein and peptide PEGylation, antibody drug conjugation (ADC), drug delivery and surface modifications.

Unlike traditional PEGs, BroadPharm's PEG linkers represent a specific, single pure chemical structure with high purity. Each product is synthesized and purified using BroadPharm's proprietary technology and characterized by modern NMR and LC/MS. BroadPharm offers over thousands of PEG linkers, Click Chemistry tools and water soluble fluorescent reagents which can empower your drug research and development, by improving drug solubility and stability, optimizing DMPK or discovering new drug delivery formats.

Our high-quality PEG linkers are water soluble, monodisperse, biocompatible, and almost aggregation-free, making them ideal for bioconjugation or crosslinking of proteins, antibodies, peptides, oligonucleotides, or solid surfaces to other molecules. Explore the use of different functional groups of PEG Linkers and Click chemistry approaches. Choose from linear, branched, or heterobifunctional PEGylation reagents with your preferred PEG length - PEG linkers products are provided as single-molecular-weight species.
