Description

Laminaritetraose is a specific oligosaccharide derived from laminarin, a β-glucan polysaccharide found in brown algae. This well-defined tetrasaccharide is a valuable biochemical tool for studying carbohydrate metabolism and enzyme specificity. It serves as a critical standard and substrate in life science research, particularly in enzymology and glycobiology. Industrial users in the biotechnology and pharmaceutical development sectors rely on its high purity for method validation and process development.

Application

• Enzyme Substrate & Assay Development: Used as a specific substrate for studying the activity, kinetics, and inhibition of β-1,3-glucanases, laminarinases, and other carbohydrate-active enzymes.
• Biochemical Research Standard: Serves as an analytical reference standard for the identification and quantification of laminarin-derived oligosaccharides via HPLC, LC-MS, or other chromatographic techniques.
• Glycobiology & Immunology Studies: Employed in research investigating the structure-activity relationships of β-glucans and their interactions with immune receptors like Dectin-1.
• Carbohydrate Chemistry: Acts as a building block or intermediate in the chemical or enzymatic synthesis of more complex glycoconjugates and labeled probes.
• Quality Control in Algal Product Manufacturing: Used as a calibration standard to monitor the enzymatic hydrolysis of laminarin and control the production of prebiotic or bioactive oligosaccharide mixtures.
