Description

Maltooctaose is a well-defined linear oligosaccharide composed of eight glucose units linked by α-1,4 glycosidic bonds. This high-purity carbohydrate standard is critical for research and industrial applications requiring precise molecular weight and structural homogeneity. It serves as an essential reference material for analytical laboratories in the food, pharmaceutical, and biotechnology sectors, enabling accurate calibration and method development.

Application

• Chromatographic Standard: Primary use as a high-purity calibration standard for HPLC, GPC, and HPAEC-PAD analysis of starch hydrolysates and complex carbohydrates.
• Enzyme Substrate & Research: Used as a specific substrate to study the activity, kinetics, and inhibition of amylases, glucosidases, and other starch-degrading enzymes.
• Food Science & Nutrition Research: Employed in metabolic studies to understand the digestion and absorption of specific carbohydrate chains and their glycemic impact.
• Biopharmaceutical Development: Acts as a model compound in the development of biosimilars and the analysis of glycosylation patterns in therapeutic proteins.
• Biomaterial & Polymer Science: Serves as a well-defined building block or precursor for synthesizing novel biodegradable polymers and hydrogels.

Quality Control

Our Maltooctaose is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and calibration purposes. A Certificate of Analysis (COA) detailing purity, chromatographic profile, and other critical parameters 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 decomposition, the container must be kept tightly sealed in a dry environment and allowed to equilibrate to room temperature before opening.
