G-Rex

G-Rex® closed-system bioreactors:
Predictable, scalable cell expansion

G-Rex scales cell therapies intelligently.

G-Rex is the only cell culture bioreactor equipped to meet current and future patient demand for immune cell therapies. G-Rex was designed for predictable, efficient, and scalable cell expansion. It enables parallel patient processing and can produce the large numbers of cells needed for cell-based therapeutics, from preclinical through commercial scale manufacturing.

Simplicity enables rapid scale up with consistent phenotypic profiles.

G-Rex is ushering in a new era of simplicity for cell therapy manufacturing. By giving cells unlimited and undisturbed access to nutrients and oxygen, G-Rex bioreactors eliminate media exchanges and the complex and expensive hardware required in integrated systems.

Greater cell throughput in a smaller footprint.

Maximize the therapeutic potential of your cell therapy through efficient and practical scale out. With one G-Rex bioreactor per patient and a small footprint per bioreactor, you can serve a high volume of patients in parallel—potentially treating 10,000 patients a year in 8x less space than conventional bioreactors.

G-Rex minimizes process development risk by using your preclinical protocols in large scale manufacturing.

Linear and predictable cell expansion in G-Rex bioreactors means a streamlined path to the clinic. Using G-Rex, the preclinical protocol and cell quality you develop directly transfers up into a large-scale closed-system process. In doing so you eliminate unnecessary process changes that often plague scale-up into complex bioreactors.

Bioreactor sizes from small scale research to commercial scale manufacturing.

G-Rex cell culture bioreactors are offered with varying footprints and media fill volumes. The portfolio is designed to accommodate the diverse needs associated with cell therapy manufacturing, supporting small scale research protocols all the way through commercial scale manufacturing.

Testimonials

“The Cell Processing Lab has shown that the culture of Tumor Infiltrating Lymphocytes (TIL), Natural Killer (NK) cells and LCL cells when using G-Rex are superior to growth bags. G-Rex allows for cell growth at higher densities and therefore less media, growth factors, cytokine and serum additives are required.”
