Description

n-Undecyl-β-D-Maltoside (CAS NO 170552-39-3) is a high-purity, non-ionic surfactant belonging to the alkyl glycoside family, specifically an undecyl maltoside. This compound is valued for its excellent detergent properties, high chemical stability, and mildness, making it a superior alternative to traditional ionic surfactants in sensitive applications. It is primarily sought after by researchers and formulators in the biotechnology, pharmaceutical, and life sciences industries for membrane protein solubilization and crystallization.

Application

• Membrane Protein Research: Critical for the solubilization, stabilization, and crystallization of integral membrane proteins for structural biology studies.
• Biochemical Assays: Used as a mild detergent in cell lysis and to maintain protein function in various in vitro diagnostic and research assays.
• Pharmaceutical Formulations: Serves as an excipient in certain drug delivery systems where gentle, non-denaturing surfactants are required.
• Chromatography: Employed in purification processes, particularly for membrane-bound proteins, using techniques like affinity chromatography.
• Virosome and Liposome Preparation: Utilized in the reconstitution of viral envelopes and preparation of lipid vesicles for vaccine and drug delivery platforms.
• Cosmetic and Personal Care: Acts as a mild surfactant and emulsifier in high-end skincare formulations due to its skin-friendly profile.
