The PEG11 spacer provides flexibility and improved aqueous compatibility, enabling effective labeling, capture, or linkage in biochemical workflows.
- Biotin tag enables affinity purification and detection.
- Maleimide group reacts selectively with sulfhydryl (thiol) groups.
- PEG11 spacer improves solubility and reduces steric hindrance.
- High purity supports reproducible conjugation chemistry.
- Supplied as an oil in multiple pack sizes for experimental flexibility.
