Mal-NH-PEG3-NH-Mal, or Bis-Mal-PEG3, is a PEG linker featuring two maleimide groups separated by a PEG3 spacer. This structure enables effective bioconjugation by forming stable covalent bonds with thiol groups, linking thiol-containing biomolecules. The PEG spacer enhances water solubility, making it an ideal choice for applications in biochemical and drug development where aqueous compatibility is essential.
Biopharma PEG offers a wide range of PEG linkers on both lab and commercial scales. Email at sales@biochempeg.com and start using a superior product for your next product R&D project.
