In the field of vaccine production and virus research, cell culture media play a critical role in supporting cell health, viability, and productivity. Among these, Cellin Vero 1 Maintenance Medium stands out as a reliable solution specifically optimized for Vero cells—a widely used continuous cell line derived from African green monkey kidney epithelial cells. This guide covers the essential aspects of Cellin Vero 1, including its composition, application scenarios, storage requirements, and how Biot Biotechnology is supporting innovation in biopharmaceutical manufacturing.

What Is Cellin Vero 1 Maintenance Medium?

Cellin Vero 1 is a specially formulated maintenance medium designed for the culture and long-term maintenance of Vero cells, particularly under conditions used in vaccine production. It offers a serum-reduced or serum-free environment, making it ideal for large-scale virus cultivation with minimal risk of contamination from animal-derived components.

This medium is a key component of Biot Biotechnology’s commitment to providing high-quality, animal-origin-free solutions for the vaccine industry.

Key Composition of Cellin Vero 1

Cellin Vero 1 is formulated to ensure optimal cell viability and virus productivity. Its composition typically includes:

• Essential amino acids and vitamins to support cellular metabolism

• Glucose and other carbohydrates as energy sources

• Balanced electrolytes to maintain osmotic pressure and pH stability

• Buffering agents (such as HEPES or sodium bicarbonate) for pH control

• Trace elements (e.g., selenium, zinc) for enzymatic activity

• Growth-promoting supplements to replace or reduce the need for fetal bovine serum (FBS)

• Antibiotics/antimycotics (optional) to prevent microbial contamination

Biot Biotechnology tailors the composition to align with customer-specific process needs, and offers customizable medium development for specialized applications.

Application in Vaccine Production

Vero cells are extensively used for propagating viruses such as poliovirus, rabies virus, measles virus, and many more. Cellin Vero 1 Maintenance Medium provides the necessary environment for:

• Viral infection and amplification during production cycles

• Post-infection cell maintenance to support extended virus harvest periods

• Adherent or microcarrier-based Vero cell cultures in bioreactors or roller bottles

• Serum-reduced process development to streamline regulatory approval and reduce variability

Biot Biotechnology supports end-to-end process optimization, ensuring that Cellin Vero 1 is integrated seamlessly into both upstream and downstream workflows.

Storage and Handling Guidelines

To ensure the stability and performance of Cellin Vero 1 Maintenance Medium, follow these best practices:

• Storage temperature: 2–8°C

• Avoid repeated freeze-thaw cycles to prevent degradation of sensitive components

• Protect from light, especially if the medium contains light-sensitive nutrients like riboflavin

• Use within the recommended shelf life (typically 6–12 months, depending on packaging)

• Pre-warm to room temperature before use to avoid shocking the cells

Sterility is essential in cell culture. Always practice aseptic technique when opening and handling the medium.
