See the latest research! We, along with our collaborators at the University of Pennsylvania, were recently published in the journal Molecular Therapy – Methods & Clinical Development. Physiologix demonstrated superior solid tumor cytotoxicity compared to cells grown in human serum. Read the full article here

Many “serum-free” supplements and complete media don’t disclose their origin or contents.

Our serum replacement is extracted from transfusion-grade blood products and comes with a full certificate of analysis.

Improved T Cell Proliferation and Transduction Efficiency Ex Vivo for CAR-T therapy in a Xeno- and Serum-Free Medium.

NB-ROC T Cell Poster

Authors: Asma Ayari, Francisco J Martinez-Becerra, Yinan Tu, Yinan Lu, and Roddy O’Connor 

Efforts need to be made to improve and develop a completely defined and xeno-free cell culture medium. Accordingly, components of animal origin used in the culture of T cells should be replaced with relevant protein sources and concentrations. Using a combination of metabolomics and process optimization, Nucleus Biologics has identified a new formulation named NB-ROC.

In this study, we tested NB-ROC on T cells isolated from the blood of three donors using standard protocols. Our data show that NB-ROC allowed cells to grow in higher numbers compared to OpTmizer™ (Fisher Scientific). This increase in proliferation did not compromise early memory phenotypes. Additionally, transduction using a GFP lentivirus was ~40% higher when cells were grown and activated in NB-ROC, which results in optimization of virus usage and reduction of manufacturing costs.

Adoptive immunotherapy involves patient T cell expansion in optimal conditions for the purpose of re-infusing their progeny as therapy. This calls for the generation and characterization of novel media supplements and formulations to boost the progress of the cell therapy market by providing physiologically relevant protein sources in concentrations suitable for biological activity. Physiologix™ XF Human Growth Factor Concentrate is a cGMP, xeno-free serum replacement that replaces supplements such as fetal bovine serum or human serum. Review this poster to view the study results of optimizing T cell media with Physisologix.
