Description

Laminarinonaose is a well-defined oligosaccharide derived from laminarin, a β-glucan found in brown algae. This high-purity compound serves as a critical standard and research tool for studying β-glucan structure, function, and biological activity. It is essential for researchers and manufacturers in the life sciences, nutraceutical, and pharmaceutical industries who require precise molecular tools for carbohydrate analysis, immunology research, and product development.

Application

• Biochemical Research Standard: Used as a reference standard for the analysis and quantification of β-glucans via techniques like HPLC, LC-MS, and SEC.
• Immunology & Cell Biology Studies: Employed to investigate the interaction of specific glucan structures with immune cell receptors (e.g., Dectin-1) and their immunomodulatory effects.
• Enzyme Substrate & Assay Development: Serves as a specific substrate for studying the activity, kinetics, and inhibition of β-glucanases and related carbohydrases.
• Nutraceutical & Functional Food R&D: Utilized in structure-activity relationship (SAR) studies to correlate glucan chain length with bioactivity for product formulation.
• Pharmaceutical Precursor Research: Acts as a starting material or intermediate for the synthesis of more complex glycoconjugates or drug delivery systems.
• Quality Control & Method Validation: Critical for developing and validating analytical methods to ensure the purity and consistency of β-glucan products.
