HS-PEG8-CH2CH2COOH is a photoelectron active form of PEG8-NHS ester, which is a water-soluble polymer that has been functionalised with an NHS moiety. The HS-PEG8-CH2CH2COOH has many applications in the field of life sciences, such as for optimising x-ray photoelectron spectroscopy (XPS) and neutravidin binding. It may also be used as a biosensor to detect arsenide, gallium and other metals. In addition, it can be used to study physicochemical properties of biomolecules.

Thiol-dPEG®8-Acid is a PEG compound with two different functional groups (also known as heterobifunctional). Unlike homobifunctional PEG compounds (same functional group on both ends), this type of compounds are more versatile as have two different anchor points. Thiol-dPEG®8-Acid is used as a linker and spacer to add a PEG moiety, via pegylation (a bioconjugation technique) to proteins, peptides, oligonucleotides, small molecules and nanoparticles.

Thiol-PEG8-acid is a PEG-based linker for PROTACs which joins two essential ligands, crucial for forming PROTAC molecules.
