NK cell receptor and ligand composition influences the clearance of SARS-CoV-2

This study correlates NK cell receptor repertoires with SARS-CoV-2 clearance. G-Rex 24-well culture plates were used to expand primary NK cells with K562 feeder cells to obtain sufficient cell numbers for functional killing assays.

Immune inactivation of anti-simian immunodeficiency virus chimeric antigen receptor T cells in rhesus macaques

This study evaluates anti-SIV CAR-T cells in rhesus macaques. Host antibodies inhibited CAR-T expansion in vivo. G-Rex were used during manufacturing to pool and expand CD4+ and CD8+ CAR-T cells prior to infusion into the animals.

Base-edited CAR T cells for combinational therapy against T cell malignancies

This paper describes base-edited, fratricide-resistant CAR-T cells targeting CD3 and CD7. Transduced cells were cultured and expanded in G-Rex 24 well, G-Rex 10, or G-Rex 100 chambers. The cells exhibited potent cytotoxicity against T-cell leukemias in vivo.
