Bis-PEG21 N-hydroxysuccinimide ester is a polyethylene glycol (PEG21) based homobifunctional NHS ester linker used for bioconjugation. It provides two reactive NHS ester termini for amine coupling and a long PEG spacer to increase solubility and flexibility, making it suitable for PROTAC and antibody-drug conjugate (ADC) synthesis.

  • PEG21 spacer increases solubility and molecular flexibility.
  • Two NHS ester groups enable efficient amine coupling.
  • Suitable as a cleavable linker in ADC and PROTAC applications.
  • High purity with analytical data and a certificate of analysis available.
  • Available in multiple pack sizes; supplier data notes a 50 MG pack though manufacturer lists 100 MG as the smallest standard pack.
