Amine-PEG3-Desthiobiotin is a PEG-based bifunctional linker combining a short PEG3 spacer, a terminal primary amine, and a desthiobiotin affinity tag. It is designed for PROTAC assembly, bioconjugation, and affinity-capture workflows where reversible binding to streptavidin/avidin aids purification and enrichment.
- Terminal primary amine for efficient coupling to carboxyl or activated ester functionalities.
- Desthiobiotin tag enables reversible affinity capture with streptavidin/avidin systems.
- PEG3 spacer improves solubility and reduces steric hindrance between binding partners.
- High chemical purity suitable for synthetic and analytical applications.
- Available in multiple small-scale quantities to support method development and optimization.
