Description

Laminarioctaose CAS NO 72621-54-6 is a well-defined oligosaccharide derived from laminarin, a β-glucan found in brown algae. This compound serves as a valuable biochemical tool and a high-purity standard for research and development in carbohydrate chemistry and life sciences. It is essential for researchers and manufacturers in the pharmaceutical, nutraceutical, and cosmetic industries who require precise, structurally characterized oligosaccharides for analytical, enzymatic, and biological studies.

Application

• Biochemical Research Standard: Used as a reference standard for the analysis and quantification of laminarin-derived oligosaccharides via HPLC, LC-MS, and other chromatographic techniques.
• Enzymatic Substrate: Serves as a specific substrate for studying the activity, kinetics, and inhibition of glucanases, laminarinases, and other carbohydrate-active enzymes.
• Immunological Studies: Employed in research to investigate the structure-activity relationships of β-glucans and their interactions with immune cell receptors like Dectin-1.
• Pharmaceutical Development: Acts as a starting material or intermediate in the development of novel carbohydrate-based therapeutics, vaccines, and drug delivery systems.
• Nutraceutical & Cosmetic Ingredient Research: Utilized in the formulation and efficacy testing of functional foods, dietary supplements, and skincare products leveraging β-glucan bioactivity.
• Glycobiology Tool: Essential for probing carbohydrate-protein interactions, cell signaling pathways, and the role of specific glucan structures in biological processes.
