Monodisperse OH-PEG8-OH (Octaethylene glycol) is a homobifunctional PEG for PEGylation, with stable HO groups that can be activated. Monodisperse homobifunctional PEG derivatives from Biochempeg are high quality crosslinkers for PEGylation of proteins and peptides, nanoparticle and surface modifications. 

OH-PEG8-OH (Octaethylene glycol) is part of a leaf extract (Murdannia Bracteata) that has been shown to have antioxidant, anti-microbial and anti-cancer properties. Applications may include ADC linker, bioconjugation, drug delivery, PEG hydrogels, cross-linking agents and surface functionalization.

Biopharma PEG offers a wide range of PEG products from lab to commercial scale in both non-GMP and GMP grades. Email at sales@biochempeg.com and start using a superior product for your next product R&D project.
