Description

Galactose Oxidase is a highly specific metalloenzyme that catalyzes the oxidation of D-galactose and certain galactose-containing polysaccharides. This product is essential for biochemical research, diagnostic assay development, and biocatalytic processes due to its precise substrate selectivity. It is a critical reagent for researchers and manufacturers in the life sciences, diagnostics, and specialty chemical synthesis sectors.

Application

• Biochemical Research & Assay Development: Used as a key enzyme in enzymatic assays to detect and quantify galactose, lactose, and related sugars.
• Diagnostic Kits: A core component in clinical diagnostic kits for measuring galactose levels, relevant for disorders like galactosemia.
• Biocatalysis & Synthesis: Employed in the selective oxidation of galactose residues in oligosaccharides and glycoconjugates for the production of fine chemicals and pharmaceutical intermediates.
• Food & Beverage Analysis: Utilized in enzymatic methods for the quality control and analysis of lactose and galactose content in dairy products and other foodstuffs.
• Glycobiology Studies: Applied in research to study cell surface carbohydrates, glycoprotein structure, and cell-cell recognition processes.
• Biosensor Fabrication: Integrated into enzyme-based biosensors for the continuous or rapid monitoring of galactose in fermentation broths or biological samples.

Quality Control

Our Galactose Oxidase is produced and tested under stringent quality management systems. Each lot is characterized for specific activity, purity, and stability to ensure performance consistency for your critical applications. A comprehensive Certificate of Analysis (COA) detailing activity, protein content, and purity is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store lyophilized powder at -20°C. Reconstituted enzyme solutions should be aliquoted and stored at -20°C or below to minimize repeated freeze-thaw cycles. The product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use.
