T-Liven PR™: Market Leading
Improvement in T-Cell Potential

T-Liven PR impacts in vitro and in vivo T-Cell Performance in three critical ways*

T-Liven PR™: Market Leading Improvement in T-Cell Potential


Compared to cells grown in FBS or AB Serum, T-Cells expanded in T-Liven PR have been show to maintain a higher percentage of Central Memory and Naive phenotypes.


When used to treat murine solid and liquid tumor models, CAR-T cells grown in T-Liven PR were found to persist longer and were effective against a secondary tumor challenge.

In both a primary tumor model and in a re-challenge model, CAR T cells grown in T-Liven PR resulted in better tumor killing effect and survival.
