Description

Maltoundecaose is a well-defined oligosaccharide composed of eleven glucose units linked by α-1,4 glycosidic bonds. This high-purity carbohydrate standard is critical for research and industrial processes requiring precise molecular weight calibration and structural reference. It serves as an essential tool for analytical laboratories and manufacturers in the biotechnology, pharmaceutical, and food science sectors seeking reliable and consistent carbohydrate materials.

Application

• Chromatographic Standard: Used as a high-purity reference standard for calibrating and validating Gel Permeation Chromatography (GPC), Size Exclusion Chromatography (SEC), and High-Performance Liquid Chromatography (HPLC) systems for polysaccharide analysis.
• Enzymatic Substrate: Acts as a specific substrate for studying the activity, kinetics, and inhibition of enzymes like α-amylase, glucoamylase, and other starch-degrading enzymes.
• Biochemical Research: Employed in carbohydrate metabolism studies, glycobiology research, and the investigation of oligosaccharide-protein interactions.
• Food Science & Nutrition: Utilized in research on dietary fiber, prebiotic effects, and the development of functional food ingredients with specific glycemic or fermentative properties.
• Pharmaceutical Excipient Development: Investigated for potential use as a carrier or stabilizer in novel drug delivery systems due to its defined molecular structure.
• Quality Control Reagent: Serves as a critical quality control material in industries producing or utilizing maltooligosaccharides, syrups, or related enzymatic products.

Quality Control

Our Maltoundecaose is produced and handled under strict quality management protocols. Each batch is subjected to rigorous analytical testing, including chromatographic purity assessment and structural confirmation, to ensure it meets the high standards required for research and industrial applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and moisture content is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). To maintain stability and prevent clumping or degradation, the container must be kept tightly sealed in a dry environment. For long-term storage, consider desiccants.
