Repligen’s Recombinant Transferrin (rTransferrin) provides process development and cell culture scientists with a robust, animal-free, and regulatory-compliant iron delivery solution. The natural mechanism for iron transport, rTransferrin eliminates performance issues commonly experienced with iron salts and chelators.
rTransferrin is a recombinant analog of human holo-transferrin expressed in a proprietary S. cerevisiae system under animal-free conditions. cGMP manufacturing standards ensure exceptional product purity and consistency, providing users dependable iron delivery while minimizing variability.

- Regulatory-compliant, animal-free
- Manufactured exclusively for cell culture
- cGMP for consistent quality
Optimal animal-free iron supplementation
Transferrin is the physiologically appropriate method for supplementing iron in cell culture, transporting iron across the cell membrane as well as stabilizing iron in media. In recent years, due to the animal-sourced nature of transferrin, the cell culture industry has turned to inorganic iron salts and chelators to improve the regulatory compliance of its processes. Although these inorganic compounds do act as iron sources, they require problematic optimization and can result in the formation of free iron radicals that cause cell toxicity as well as impact end-product quality. Repligen's rTransferrin provides all the benefits of optimized iron transport while enabling you to maintain an animal-free, defined, and regulatory-compliant process.
Flexible liquid format
Repligen's rTransferrin is formulated as a convenient liquid product, making it easy to use at any scale. Simply open and dilute into cell culture media; no thawing, reconstitution, or buffer preparation necessary.
Quality and regulatory support
Repligen's rTransferrin is used in approved cell-based manufacturing processes and in clinical processes at all stages of the development pathway. Dedicated quality, regulatory, and technical support is available for rTransferrin to assist customers at all stages of development through regulatory filing and commercial approval.
