Bis-PEG3-NHS ester is a noncleavable, three-unit polyethylene glycol (PEG) linker bearing N-hydroxysuccinimide (NHS) ester termini for amine-directed bioconjugation and antibody-agent conjugation applications.

  • Provides two NHS ester termini for efficient amine coupling.
  • Three-unit PEG spacer increases hydrophilicity and reduces steric hindrance.
  • Noncleavable design yields stable conjugation in antibody-drug conjugate constructs.
  • High purity suitable for research applications.
  • Stable as a powder at -20°C for long-term storage; limited stability in solution.
