Maleimide(Mal) PEG

Monodispersed Maleimide PEG (PEG-Mal) is a type of PEG Linker with a maleimide (Mal) group. These compounds specifically react with sulfhydryl (thiol/SH) groups to form stable thioether linkages when the pH is between 6.5 and 7.5. This selective reactivity makes PEG-Mal an essential tool in bioconjugation, allowing for precise and stable modifications of proteins, peptides, and other surfaces with available sulfhydryl groups, thereby enhancing the functionality and stability of therapeutic agents.

Biopharma PEG offers a wide range of monodispersed MaleimidePEG linkers 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.
