Bis-PEG3-NHS ester is a non-cleavable PEG-based bifunctional linker containing two N-hydroxysuccinimide (NHS) ester reactive groups used for bioconjugation and antibody-drug conjugate (ADC) construction. The three-unit PEG spacer increases hydrophilicity and solubility, while the NHS esters enable efficient coupling to primary amines on proteins and peptides.
- Non-cleavable 3-unit PEG linker for stable conjugation.
- Contains two NHS ester groups for bioconjugation to primary amines.
- Improves solubility and hydrophilicity of conjugates.
- Available in multiple package sizes, including 500 mg.
- Provided with SDS, COA, and product data sheet for quality and safety information.
