Biotin-PEG7-amine is a PEG-based biotinylation reagent containing a seven-unit polyethylene glycol spacer terminating in a primary amine. It is used as a linker in PROTAC synthesis and for bioconjugation to introduce a biotin tag for affinity capture and detection.
- PEG7 spacer improves solubility and reduces steric hindrance.
- Terminal primary amine enables coupling to activated carboxyl groups or NHS esters.
- Biotin tag allows efficient affinity capture using streptavidin or avidin systems.
- Compatible with standard peptide- and small-molecule coupling chemistries.
- High purity supports synthetic and analytical applications.
