Description

α-Cyclodextrin, Sulfated Sodium Salt is a chemically modified derivative of α-cyclodextrin, where sulfate groups are introduced to enhance its solubility and biological activity. This modification creates a powerful anionic cyclodextrin with superior binding capabilities for cationic molecules and proteins, making it a valuable tool for research and formulation. It is primarily utilized by scientists and manufacturers in the pharmaceutical, biotechnology, and analytical chemistry sectors for applications ranging from drug delivery to enzyme stabilization.

Application

• Pharmaceutical Research & Drug Delivery: Acts as a complexing agent to improve the solubility, stability, and bioavailability of poorly water-soluble cationic drugs.
• Protein & Enzyme Stabilization: Used to stabilize proteins and enzymes in diagnostic kits and biochemical assays by preventing aggregation.
• Chromatography & Electrophoresis: Serves as a chiral selector or additive in capillary electrophoresis and HPLC for the separation of enantiomers and charged analytes.
• Cell Culture & Molecular Biology: Employed to deliver membrane-impermeable compounds into cells or to study protein-ligand interactions.
• Catalysis: Can be used to create supramolecular catalysts where the sulfated cavity provides a unique micro-environment for chemical reactions.
• Cosmetic Formulations: Functions as a stabilizer and delivery agent for active ingredients in advanced cosmetic products.
