We are deeply saddened by the passing of Dr. William J. Rutter—a visionary scientist, mentor, entrepreneur, and close friend to many at InVitria. He passed away on July 11, 2025, at the age of 97. Few scientists have shaped modern biotechnology as deeply as Dr. Rutter. His research laid the groundwork for recombinant insulin, genetically …
Overview ITS Animal-Free™ ITS Animal-Free (ITS AF), InVitria’s 100x cocktail of Insulin, Transferrin, and Selenium that is completely animal-origin-free, is essential for culture of all mammalian cell types including iPSCs. ITS AF can be conveniently supplemented into custom media formulations to replace the core components of serum. This reduces variability, eliminates safety and regulatory hurdles, …
Overview Efficient iron delivery plays a critical role in maintaining cell health, supporting proliferation, and maximizing therapeutic productivity. However, serum-derived transferrin introduces variability, regulatory risk, and the potential for contamination. This application note demonstrates how Optiferrin, a recombinant transferrin for iron delivery in serum-free media, provides a consistent and animal-origin-free alternative. It mirrors native transferrin …
Reading time: 4 minutes What happens when your biologics pipeline depends on the reliability of an international border? For many manufacturers still using plasma-derived components like albumin or transferrin, that’s not a hypothetical. It’s baked into their supply chain. Across the U.S.–Mexico border, more than 50 plasma centers depend on daily crossings from Mexican nationals …
Overview This application note demonstrates the use of Optibumin® 25—an animal-origin-free recombinant HSA—for low-DMSO cryopreservation of UC-MSCs. Optibumin matched or outperformed blood-derived HSA, even at DMSO levels as low as 1%, supporting safer, regulatory-friendly workflows for cell therapy manufacturing. Key Findings Maintains MSC viability at 1–2.5% DMSO Reduces apoptosis vs. no-albumin controls Performs as well …
Download the infographic to see how InVitria’s chemically defined, animal-origin-free components optimize each step of the CAR-T manufacturing process—improving consistency, viability, and yield.
Download the poster to see how Optibumin® rHSA improves CAR-T manufacturing by reducing cell loss during washing, preserving phenotypes, and enabling safer low-DMSO cryopreservation with stronger post-thaw recovery.
