Description

Riboflavin-Binding Protein From Egg White ~10 U/Mg is a highly purified, biologically active protein derived from egg white, specifically designed to bind riboflavin (vitamin B2). This specificity makes it an invaluable reagent for analytical and research applications where the quantification, isolation, or study of riboflavin is required. It is essential for laboratories and manufacturers in the food science, nutraceutical, and life science research sectors seeking reliable, high-affinity binding agents.

Application

• Analytical Assay Development: Used as a critical component in ELISA, RIA, or other immunoassays for the precise quantification of riboflavin in complex matrices like food, beverages, and biological fluids.
• Food & Nutritional Analysis: Employed in quality control laboratories to accurately measure vitamin B2 content in fortified foods, infant formula, dietary supplements, and animal feed.
• Biochemical Research: Serves as a tool for studying riboflavin transport, metabolism, and protein-ligand interactions in academic and pharmaceutical research settings.
• Diagnostic Kits: Incorporated into commercial diagnostic test kits for the assessment of riboflavin status in clinical or veterinary samples.
• Affinity Chromatography: Immobilized on solid supports to create affinity columns for the purification and isolation of riboflavin or related compounds from mixtures.
• Pharmaceutical Development: Utilized in stability testing and formulation studies for riboflavin-containing pharmaceuticals to monitor vitamin potency.
