Description

Enterotoxin Type B, Staphylococcus Aureus is a potent protein exotoxin produced by the bacterium *Staphylococcus aureus*. This product is critical for research, diagnostic, and quality control applications where the detection and study of staphylococcal enterotoxins are paramount. It is primarily utilized by biotechnology firms, pharmaceutical R&D laboratories, and food safety testing facilities to develop assays, validate detection methods, and ensure product safety.

Application

• Immunoassay Development & Calibration: Serves as a critical reference standard and calibrant for ELISA, lateral flow, and other immunoassays designed to detect Staphylococcal Enterotoxin B (SEB).
• Food Safety Testing: Used as a positive control in testing kits to monitor for SEB contamination in food products, a major cause of foodborne illness.
• Biomedical & Toxin Research: Essential for studying the structure, function, mechanism of action, and pathophysiology of SEB in academic and pharmaceutical research settings.
• Diagnostic Kit Manufacturing: A key raw material for the production of in-vitro diagnostic (IVD) reagents and kits for clinical and environmental testing.
• Vaccine & Antitoxin Development: Employed in the research and development of potential vaccines and therapeutic antitoxins against SEB exposure.
• Quality Control & Method Validation: Acts as a benchmark in laboratory quality control protocols to validate the accuracy and sensitivity of analytical methods.

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is characterized for identity, purity, and biological activity using advanced analytical techniques. Certificates of Analysis (COA) detailing specific test results, including purity by HPLC and functional activity, are available upon request to support your regulatory and quality assurance needs.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This material is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature before opening to minimize moisture uptake. For extended storage, consider under inert atmosphere.
