InVitria Launches Optibumin® 25, the First Recombinant 25% Human Serum Albumin for Closed-System Biomanufacturing

InVitria, a leading developer of recombinant, chemically defined components for biomanufacturing, has announced the launch of Optibumin® 25, the first and only recombinant human serum albumin (rHSA) available as a 25% solution. Designed for closed-system workflows, Optibumin 25 is a high-purity alternative to plasma-derived albumin, enabling safer, more consistent manufacturing in cell and gene therapy applications.

Optibumin® 25 – a 25% recombinant human serum albumin (rHSA) solution developed by InVitria – offers an animal-origin-free, GMP-compliant alternative to plasma-derived albumin for closed-system biomanufacturing.

For decades, plasma-derived HSA has presented regulatory and supply chain challenges, including batch variability and pathogen risks. Optibumin 25 eliminates these issues by offering a chemically defined, animal-origin-free, GMP-compliant alternative. It supports regulatory compliance while improving scalability, sterility, and formulation performance.

“Optibumin 25 directly replaces plasma-derived 25% HSA while enhancing process control and reducing regulatory risk,” said Scott Deeter, CEO at InVitria. “It enables the kind of consistency required for clinical and commercial-scale production.”

Manufactured in an ISO 9001-certified, cGMP-compliant facility, Optibumin 25 is optimized for downstream processing, formulation, and cryopreservation workflows. The product is currently available in 100 mL single-use bags and is suitable for integration into viral vector manufacturing, stem cell preservation, vaccine formulation, and regenerative medicine.

Key Benefits:

• First recombinant 25% HSA designed for closed systems
• Animal-origin-free and chemically defined
• GMP-ready and scalable to commercial volumes
• Stable, sterile, and contamination-resistant
