Description

Ovalbumin CAS NO 9006-50-2 is the major protein component of egg white, serving as a highly purified reference standard and functional ingredient. Its consistent quality and well-characterized properties make it indispensable for research, diagnostics, and specialized manufacturing processes. This protein is critical for suppliers and formulators in the biotechnology, pharmaceutical, and food science industries who require a reliable and pure albumin source.

Application

• Biochemical Research & Standard: Used as a primary protein standard in electrophoresis (SDS-PAGE), chromatography calibration, and immunological assays.
• Diagnostic Reagent Manufacturing: Acts as a stabilizer, carrier protein, or blocking agent in ELISA kits, lateral flow assays, and other in vitro diagnostic products.
• Cell Culture & Microbiology: Employed as a nutrient supplement in certain culture media formulations and as a coating agent to promote cell attachment.
• Pharmaceutical Excipient: Functions as a stabilizer or bulking agent in vaccine formulations and other biopharmaceutical products.
• Food Science Research: Studied for its functional properties, including foaming, gelling, and emulsification, in model food systems.
• Allergen Reference Material: Serves as a purified reference for the detection and quantification of egg allergens in food safety testing.
