Description

6-Sialyl-D-Lactose* CAS NO 56144-12-8 is a complex, high-purity human milk oligosaccharide (HMO) derivative, a critical component for advanced nutritional and biomedical research. This compound is valued for its role as a structural analog and precursor in the study of glycan-mediated biological processes, including immune modulation and pathogen adhesion. It is primarily required by research institutions and manufacturers in the pharmaceutical development, infant formula fortification, and diagnostic reagent sectors seeking to develop next-generation bioactive ingredients.

Application

• Pharmaceutical Research & Development: As a key reference standard and precursor for synthesizing glycoconjugates, glycan arrays, and novel therapeutics targeting lectin receptors.
• Infant Nutrition Science: Used in research to study the prebiotic and anti-infective properties of human milk oligosaccharides (HMOs) for advanced formula development.
• Diagnostic Reagent Manufacturing: Serves as a critical component in the production of assay kits for detecting specific glycosyltransferases or glycan-binding proteins.
• Glycobiology Studies: Essential tool for investigating cell-cell communication, microbial adhesion, and immune system modulation mediated by sialylated glycans.
• Bioconjugation & Probe Synthesis: Acts as a starting material for creating fluorescently labeled or biotinylated glycan probes for flow cytometry and microscopy.
• Standards for Analytical Methods: Provides a high-purity standard for HPLC, LC-MS, and NMR analysis in quality control and metabolic studies.
