Certification and Compliance for the highest avidin quality

Furthermore, E-Proteins plays a crucial role in avidin certification in the pharmaceutical and diagnostic sectors. The company’s production of avidin strictly follows ISO-9001:2015 standards, ensuring high-level quality management. The GMP avidin certification, approved by the Belgian National Health Agency, highlights the company’s dedication to providing a drug substance that aligns with its intended use.

Virus Safety Measures and Sterile Certification

E-Proteins undergoes yearly audits by the National Veteran Agency to ensure regulatory compliance due to the animal origin of avidin. The company has developed several methods for virus inactivation and removal, selecting three to maintain maximum product activity. The Virus Inactivation/Removal Certification process is rigorous and lasts about nine months.

In pursuit of sterile certification, E-Proteins collaborates closely with specialized companies, ensuring that the certified sterile avidin meets the highest industry standards. E-Proteins pharmacists oversee the release of the certified sterile avidin as a Drug Product, enhancing its suitability for injectable applications in clinical trials and ensuring adherence to the highest safety and efficacy standards.


In summary, E-Proteins firmly establishes itself as a leader in the binding protein sector, demonstrating an unwavering dedication to maintaining the highest quality standards in avidin production. The company’s rigorous certification processes and commitment to providing exceptional products and services emphasize its role in advancing the life sciences sector.
