Tr-PEG3-OH is a non-cleavable, three-unit polyethylene glycol (PEG) linker intended for research use in the synthesis of antibody-drug conjugates (ADCs). It provides a short hydrophilic spacer that improves solubility and linker flexibility while remaining stable under biological conditions.
- Non-cleavable 3-unit polyethylene glycol linker suitable for ADC construction.
- Improves solubility and hydrophilicity of conjugates.
- Short PEG spacer reduces steric hindrance between antibody and payload.
- High purity supports reproducible conjugation chemistry.
- Defined molecular weight for consistent analytical characterization.
