Description

3-o-Sulfo-D-Galactosyl-1-1'-n-Heptadecanoyl-D-Erythro-Sphingosine (Ammonium Salt) is a high-purity, synthetic sulfated glycosphingolipid derivative, specifically a sulfatide analog. This compound is a critical biochemical tool for studying lipid-protein interactions, membrane biology, and signaling pathways in neurological and immunological research. It is essential for researchers and manufacturers in the pharmaceutical and biotechnology sectors who require well-defined, structurally complex lipids for assay development, drug discovery, and as reference standards.

Application

• Biochemical Research Reagent: Used as a high-purity standard and substrate in enzymatic assays, particularly for studying sulfatase and glycosyltransferase activities.
• Neuroscience Studies: Critical for investigating the role of sulfatides in myelin function, neural development, and the pathology of diseases like metachromatic leukodystrophy (MLD) and multiple sclerosis.
• Immunology & Cell Signaling: Serves as a ligand or antigen to study immune cell activation, antigen presentation, and receptor-mediated signaling pathways.
• Lipidomics & Analytical Standards: An essential reference compound for mass spectrometry-based lipidomic profiling and method validation in analytical laboratories.
• Pharmaceutical Development: Employed in screening platforms and as a key intermediate in the development of therapeutic agents targeting lipid metabolism disorders.
• Membrane Biophysics: Used to create model membranes (liposomes, bilayers) to study lipid raft dynamics and membrane protein interactions.
