Description

Iv(3)-Neuac-Lcose4Cer CAS NO 103842-51-9 is a complex, high-purity glycosphingolipid derivative, specifically a sialylated lacto-series glycosphingolipid. This compound is a critical biochemical tool and reference standard for research in glycobiology, immunology, and cell signaling. It is primarily utilized by research institutions, diagnostic manufacturers, and pharmaceutical companies engaged in the development of novel therapeutics and diagnostic assays. Its defined structure makes it essential for studying carbohydrate-protein interactions, cell adhesion processes, and as a precursor in synthetic pathways.

Application

• Biochemical Research: As a high-purity reference standard for the study of ganglioside and glycosphingolipid metabolism, function, and biosynthesis.
• Diagnostic Development: Used as a critical antigen or coating material in the development of immunoassays and biosensors for detecting specific antibodies or lectins.
• Pharmaceutical R&D: Serves as a key intermediate or target molecule in drug discovery programs focused on cancer, infectious diseases, and neurological disorders.
• Cell Biology Studies: Employed to investigate cell surface recognition, signal transduction events, and the role of specific glycan structures in cellular communication.
• Enzymology: Acts as a specific substrate for characterizing the activity of glycosyltransferases, neuraminidases (sialidases), and other glycan-modifying enzymes.

Quality Control

Every batch of Iv(3)-Neuac-Lcose4Cer is manufactured and analyzed under strict quality protocols to ensure identity, purity, and consistency. Our products undergo rigorous quality testing, including advanced chromatographic and spectroscopic methods, to ensure compliance with research-grade standards. A comprehensive Certificate of Analysis (COA) detailing purity, identity confirmation (NMR, MS), and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dedicated freezer. This product is hygroscopic (moisture-sensitive); allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and hydrolysis. For long-term storage, consider storing under an inert atmosphere such as argon or nitrogen.
