Description

n-Acetyllactosamine is a high-purity, advanced carbohydrate building block and a key disaccharide derivative of lactose. This compound is essential for research and synthesis in glycobiology, serving as a crucial precursor for the preparation of complex oligosaccharides, glycoconjugates, and glycan arrays. It is primarily utilized by scientists and manufacturers in the pharmaceutical, biotechnology, and diagnostic sectors for developing novel therapeutics, probes, and analytical standards.

Application

• Glycobiology Research: A fundamental substrate for studying glycosyltransferase enzymes, carbohydrate-protein interactions, and cell surface recognition events.
• Pharmaceutical Intermediate: Serves as a critical building block for the synthesis of complex oligosaccharides used in drug discovery, particularly for cancer, inflammation, and infectious disease targets.
• Diagnostic Reagent Production: Used in the manufacture of labeled probes and standards for glycan analysis techniques like HPLC, MS, and lectin arrays.
• Bioconjugation: Acts as a starting material for creating neoglycoconjugates, glycopolymers, and surface-modified materials for biomedical applications.
• Enzyme Substrate: Employed as a specific substrate for β-1,4-galactosyltransferase and other enzymes in enzymatic synthesis cascades.
• Standards and Controls: Provides a high-purity reference standard for quality control in biopharmaceutical production and academic research.

Quality Control

Our n-Acetyllactosamine is produced under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for sensitive research applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We support compliance with relevant research and development standards.

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) and light-sensitive (store away from light); therefore, containers must be kept tightly sealed in a desiccated environment after opening to maintain stability and prevent decomposition.
