Description

Laminariheptaose is a defined, high-purity oligosaccharide derived from laminarin, a β-glucan polysaccharide found in brown algae. This compound is a valuable biochemical tool for studying carbohydrate-protein interactions and immune system modulation. It serves as a critical standard and substrate in life science research, pharmaceutical development, and the nutraceutical industry for investigating β-glucan receptors and structure-activity relationships.

Application

• As a reference standard for the chromatographic analysis and quantification of β-glucan oligomers.
• As a defined substrate for enzymatic studies of laminarinases, glucanases, and other carbohydrate-active enzymes.
• In immunological research to investigate the structure-specific activation of immune cells via Dectin-1 and other pattern recognition receptors.
• For the structure-activity relationship (SAR) study of β-glucans in drug discovery and nutraceutical development.
• As a molecular tool in glycobiology for probing carbohydrate-binding proteins and lectins.
• In the development of functional food ingredients and immune-modulating supplements with precise structures.
