Biotin-PEG2-Iodide (CAS: 292843-75-5) is a biotinylation reagent with a biotin group, PEG2 spacer, and reactive iodide. The biotin binds strongly to avidin or streptavidin, enabling efficient labeling, detection, and purification of biomolecules. The PEG2 spacer improves water solubility and minimizes steric hindrance, while the iodide group supports nucleophilic substitution reactions for versatile bioconjugation.
Key Features:
- Biotin Group: Binds tightly to avidin or streptavidin for easy purification and detection.
- PEG2 Spacer: Enhances solubility, reduces aggregation, and improves molecular accessibility.
- Iodide Group: Enables nucleophilic substitution for efficient biomolecule labeling.
Applications:
- Bioconjugation: Labels proteins, peptides, and other biomolecules for diagnostics and therapeutic research.
- Molecular Biology: Supports protein interaction studies, localization tracking, and biochemical assays.
How to Use:
- Storage: Store at -20°C, away from light and moisture, for long-term stability.
- Solubility: Dissolves well in water, DMSO, and DMF for chemical reactions.
Biotin-PEG-Iodide is a valuable tool for researchers in biotechnology, molecular biology, and pharmaceutical development, offering high binding efficiency and excellent solubility.
