Mal-PEG1-NHS ester is a PEG-based bifunctional linker containing a maleimide group and an N-hydroxysuccinimide (NHS) ester. It is used for bioconjugation in the synthesis of antibody-drug conjugates (ADCs) and proteolysis-targeting chimeras (PROTACs), enabling selective thiol-to-amine coupling via maleimide and NHS chemistries.

  • Bifunctional maleimide and NHS ester chemistry for thiol and amine coupling.
  • PEG spacer increases solubility and reduces steric hindrance.
  • Non-cleavable linker suitable for ADC and PROTAC synthesis.
  • Available in multiple pack sizes, including 1 g for preparative use.
  • Molecular weight 310.26 g/mol and formula C13H14N2O7.
