Description

Isoglobotriaose is a defined, high-purity trisaccharide carbohydrate used as a critical standard and reagent in glycobiology research. This compound matters for its role in elucidating complex carbohydrate structures and functions, particularly those related to glycosphingolipid metabolism and cell recognition processes. It is essential for researchers and manufacturers in the pharmaceutical, diagnostic, and life science sectors who require precise tools for glycan analysis, enzyme substrate studies, and the development of novel therapeutics.

Application

• Glycobiology Research Standard: Serves as a primary reference standard for the identification and quantification of isoglobotriaosylceramide (iGb3) and related glycolipids in analytical methods like HPLC and MS.
• Enzyme Activity Assays: Used as a specific substrate to study the activity, inhibition, and kinetics of glycosidases and glycosyltransferases involved in sphingolipid pathways.
• Diagnostic Development: Employed in the development and calibration of diagnostic assays targeting carbohydrate antigens and antibodies, particularly in immunology and oncology.
• Pharmaceutical Intermediates: Acts as a key building block or precursor in the synthesis of more complex glycoconjugates for potential therapeutic applications.
• Cell Biology Studies: Utilized to probe cell surface interactions, signal transduction events, and the biological roles of iGb3 in immune system modulation.
• Biomarker Discovery: Aids in the discovery and validation of glycan-based biomarkers for various diseases by providing a pure structural reference.
