NHS-PEG2-SS-PEG2-NHS is a cleavable four-unit polyethylene glycol (PEG) linker bearing N-hydroxysuccinimide (NHS) esters at both termini. It is designed for use in bioconjugation workflows, including the synthesis of antibody-drug conjugates (ADCs), providing a reducible disulfide-containing spacer to improve solubility and enable payload release under reducing conditions.
- Cleavable disulfide-containing PEG spacer for controlled payload release.
- Terminal NHS esters for efficient conjugation to amines.
- Four-unit PEG improves aqueous solubility of conjugates.
- Suitable for ADC synthesis and general bioconjugation workflows.
- Intended for research use; handle according to safety data sheet instructions.
