Description

3'-Sialyllactose is a significant human milk oligosaccharide (HMO) and a key sialylated carbohydrate. This compound is of high commercial and research interest due to its prebiotic and anti-pathogenic properties, which support infant gut health and immune system development. It is primarily utilized by manufacturers in the infant formula, nutraceutical, and pharmaceutical industries to create advanced nutritional products and for biochemical research applications.

Application

• Infant Formula Fortification: A critical additive to mimic the composition and functional benefits of human breast milk, promoting healthy gut microbiota and cognitive development.
• Nutraceutical & Dietary Supplements: Used in adult and pediatric nutritional products for its prebiotic effects and potential immune-modulating benefits.
• Pharmaceutical Research: Serves as a standard reference material and an active ingredient in studies related to gastroenterology, immunology, and microbiology.
• Microbiome Studies: Employed as a selective growth substrate for beneficial bacteria like Bifidobacteria in probiotic and synbiotic formulations.
• Glycobiology & Biochemistry: Essential for enzymatic studies, receptor-ligand interaction research, and the synthesis of more complex glycoconjugates.
• Functional Food & Beverages: Incorporated into health-focused food products designed to enhance digestive wellness and overall health.

Quality Control

Our 3'-Sialyllactose is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via NMR and MS, to ensure it meets high-purity standards suitable for nutritional and research applications. Certificates of Analysis (COA) detailing purity, impurities, and moisture content are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This product is hygroscopic (moisture-sensitive). Allow the sealed container to reach room temperature before opening to prevent condensation and moisture absorption. For short-term use, store desiccated at 2-8°C.
