Description

Dextran Sucrase is a specialized enzyme (EC 2.4.1.5) that catalyzes the synthesis of dextran from sucrose. This product is critical for the controlled production of dextran polymers with specific molecular weights and branching patterns. It is essential for manufacturers in the pharmaceutical, food technology, and biochemical research sectors requiring precise polysaccharide synthesis.

Application

• Pharmaceutical Excipient Production: Key enzyme in the synthesis of clinical-grade dextran used as a plasma volume expander and drug delivery vehicle.
• Chromatography Media: Used to manufacture dextran-based beads and gels (e.g., Sephadex) for size-exclusion and affinity chromatography.
• Food Industry: Production of dextran as a texturizer, stabilizer, or prebiotic fiber in certain food products.
• Biochemical Research: Tool enzyme for studying glucosyltransferase mechanisms and synthesizing defined oligosaccharides.
• Diagnostic Reagents: Used in the formulation of certain diagnostic kits and agglutination tests.
• Dental Plaque Research: Study of glucan formation by oral bacteria and development of anti-caries agents.
