Description

Epi-n-Acetyl-Lactosamine is a high-purity, advanced carbohydrate building block and a key intermediate in glycobiology research. This compound is critical for the synthesis of complex oligosaccharides, glycoconjugates, and glycan arrays used to study carbohydrate-protein interactions. It is essential for researchers and manufacturers in the pharmaceutical, biotechnology, and diagnostic sectors who are developing novel therapeutics, vaccines, and analytical tools targeting glycan-mediated biological processes. The material is supplied as a high-quality standard to ensure reliable and reproducible results in sensitive applications.

Application

• Glycobiology Research: A fundamental building block for the de novo chemical and enzymatic synthesis of biologically relevant oligosaccharides and N-linked glycans.
• Pharmaceutical Development: Used as a key intermediate in the research and production of glycan-based vaccines, antibody-drug conjugates (ADCs), and other biopharmaceuticals.
• Diagnostic Reagent Synthesis: Employed in creating labeled probes and array components for studying carbohydrate-binding proteins (lectins) and antibodies in diagnostic assays.
• Enzymatic Substrate: Serves as a substrate for glycosyltransferases in enzymatic cascade reactions to build more complex carbohydrate structures.
• Chemical Biology Tools: Utilized to develop activity-based probes and inhibitors for glycosidases and glycosyltransferases to elucidate their biological functions.
• Standards and References: Provides a high-purity analytical standard for quality control and method development in HPLC, MS, and NMR analysis of glycans.

Quality Control

Our Epi-n-Acetyl-Lactosamine is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including HPLC for purity and identity confirmation (NMR, IR), to ensure it meets the high standards required for research and development. A detailed Certificate of Analysis (COA) documenting purity, residual solvents, and other critical parameters is provided with every shipment. We support compliance with relevant guidelines for advanced pharmaceutical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C or as indicated on the label or COA. This product is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions to maintain stability and purity. Allow the sealed container to reach ambient temperature before opening to prevent condensation.
