Description
Alpha Cyclodextrin Sulfated High (DS 8–11)
Alpha-cyclodextrin, sulfated (high sulfate, degree of substitution 8–11), is a highly functional cyclodextrin derivative designed to provide strong electrostatic interaction in systems involving small molecules and proteins. By increasing the level of sulfation, this material achieves a significantly higher negative charge density, enabling high-affinity binding and enhanced interaction capabilities in biochemical and analytical applications.
Manufactured by Michigan Diagnostics LLC, this product is produced with tight control over substitution levels to ensure consistent performance and reproducibility.
Structural and Functional Characteristics
The alpha-cyclodextrin backbone provides a compact cavity suitable for small molecules. When heavily sulfated (DS 8–11), the molecule transitions toward electrostatic interaction dominance, while still retaining some inclusion capability.
The increased charge density enhances binding to positively charged molecules, making it highly effective in systems where charge-based interaction is critical.
Key Properties
- Degree of Substitution: 8–11
- Charge Profile: Strongly anionic
- Water Solubility: Very high
- Cavity Size: ~4.7–5.3 Å
