Description

Alginate Lyase CAS NO 40591-57-9 is a specialized enzyme that catalyzes the depolymerization of alginate, a polysaccharide found in brown algae. This enzymatic activity is critical for breaking down alginate into oligosaccharides or monosaccharides, unlocking its value across diverse industrial and research sectors. It is an essential tool for biotechnology, pharmaceutical, and food science professionals requiring precise polysaccharide modification.

Application

• Biopharmaceutical Production: Used in the downstream processing of bacterial fermentation, particularly for the isolation and purification of biopolymers like alginate from microbial sources.
• Biofuel & Biochemical Research: Facilitates the enzymatic hydrolysis of algal biomass for the production of fermentable sugars in biofuel applications.
• Food & Nutraceutical Industry: Employed to modify texture, generate prebiotic alginate oligosaccharides, or recover bioactive compounds from seaweed.
• Biomedical & Tissue Engineering: Used to gently degrade alginate-based hydrogels for cell recovery or to create tailored scaffold structures.
• Analytical & Diagnostic Applications: Serves as a reagent in assays to quantify alginate content or study alginate structure-function relationships.
• Cosmeceuticals: Applied in the production of low-molecular-weight alginate derivatives for enhanced skin absorption and functionality.

Quality Control

Our Alginate Lyase is produced and tested under stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for specific activity, purity, and absence of contaminating proteases or nucleases. A comprehensive Certificate of Analysis (COA) detailing assay results, stability data, and storage recommendations is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent moisture condensation. For short-term use, aliquoting is recommended to avoid repeated freeze-thaw cycles.
