Cas-CLOVER is a novel high-fidelity nuclease for safe and robust generation of TSCM-enriched allogeneic CAR-T cells
Cas-CLOVER is characterized as a high-fidelity nuclease for generating allogeneic CAR-T cells with high stem cell memory content (TSCM). It shows low off-target activity. The manufacturing process for P-BCMA-ALLO1 utilized G-Rex 100M vessels for cell culture and expansion.

TEM8 Tri- specific Killer Engager binds both tumor and tumor stroma to specifically engage natural killer cell anti- tumor activity
A Tri-specific Killer Engager (TriKE) targeting TEM8 (cam1615TEM8) was developed to redirect NK cells against both tumor and stromal cells. The molecule enhanced NK cell proliferation and antitumor efficacy in mouse models. Enriched NK cells for in vivo experiments were expanded in G-Rex 6-well plates.

Local delivery of interleukin 7 with an oncolytic adenovirus activates tumor-infiltrating lymphocytes and causes tumor regression
An oncolytic adenovirus expressing human IL-7 (Ad5/3-E2F-d24-hIL7) was developed to activate TILs within the tumor microenvironment. It increased T cell infiltration and caused tumor regression in animal models. G-Rex culturing plates were used for the rapid expansion of PBMCs in control experiments.

Neutralizing antibodies protect mice against Venezuelan equine encephalitis virus aerosol challenge
This study isolates and characterizes neutralizing monoclonal antibodies against Venezuelan equine encephalitis virus (VEEV) from mice and humans. These antibodies target the E2 glycoprotein and protect mice from lethal aerosol challenge. G-Rex devices were used to expand hybridoma clones in serum-free medium.

Feeder-Cell-Free and Serum-Free Expansion of Natural Killer Cells Using Cloudz Microspheres, G-Rex6M, and Human Platelet Lysate
The authors developed a feeder-free, xeno-free protocol for NK cell expansion using NK Cloudz microspheres in G-Rex6M vessels with human platelet lysate. The method achieved ~387-fold expansion in 10 days with high purity and cytotoxicity, offering a scalable alternative to feeder cell-based methods.

BOXR1030, an anti-GPC3 CAR with exogenous GOT2 expression, shows enhanced T cell metabolism and improved anti-cell line derived tumor xenograft activity
The authors developed BOXR1030, a GPC3-targeted CAR T cell co-expressing GOT2 to enhance metabolism. T cells were expanded in G-Rex 10 or 100 units. BOXR1030 demonstrated superior in vivo antitumor activity, reduced exhaustion, and better persistence in solid tumor xenograft models compared to control CARs.

Genome Editing With TALEN, CRISPR-Cas9 and CRISPR-Cas12a in Combination With AAV6 Homology Donor Restores T Cell Function for XLP
This study demonstrates that genome editing with TALEN or CRISPR can restore SAP expression and function in T cells from XLP patients. PBMC stimulation and culture were performed in G-Rex 24 plates. Edited cells showed physiological SAP levels and restored immune functions, suggesting a viable therapeutic approach.

A SUPPLY CHAIN CRISIS STORY: CULTURE BAG SHORTAGE ENFORCED VALIDATION OF AN ALTERNATIVE EXPANSION SYSTEM FOR CAR T CELLS
Due to supply chain shortages, the authors validated G-Rex vessels as an alternative to Wave bioreactors for CAR T expansion. G-Rex 1L vessels produced 2-4 billion T cells with >90% viability and comparable phenotype/function, using significantly less media and labor than the Wave system.
