Description

Undecyl Maltoside-Sol-Grade is a high-purity, non-ionic surfactant belonging to the alkyl maltoside family, specifically designed for demanding solubilization applications. Its value lies in its exceptional ability to gently solubilize and stabilize membrane proteins and other sensitive biomolecules without denaturing them, making it a critical reagent for structural biology and biophysical research. This Sol-Grade product is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and life sciences sectors who require reliable, high-performance detergents for protein purification, crystallization, and analytical assays.

Application

• Membrane Protein Solubilization & Purification: Primary application for extracting and stabilizing integral membrane proteins for structural and functional studies.
• Biophysical & Structural Biology: Used in techniques like X-ray crystallography, cryo-electron microscopy (cryo-EM), and NMR spectroscopy to maintain protein native conformation.
• Liposome & Vesicle Preparation: Acts as a gentle detergent for forming and manipulating model membrane systems.
• Cell Lysis & Organelle Isolation: Effective for disrupting cell membranes while preserving organelle and protein complex integrity.
• Diagnostic Assay Development: Utilized as a stabilizing agent in immunoassays and other diagnostic kits that involve membrane-bound targets.
• Pharmaceutical Formulation: Can serve as an excipient for enhancing the solubility of poorly water-soluble active pharmaceutical ingredients (APIs).

Quality Control

Our Undecyl Maltoside-Sol-Grade is manufactured under strict quality systems to ensure batch-to-batch consistency and high performance for critical research applications. Each lot is subjected to rigorous analytical testing, including HPLC for purity and critical micelle concentration (CMC) verification. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and functional performance is provided with every shipment to support your quality assurance and regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 15-25°C. This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent absorption of atmospheric moisture, which can affect performance.
