GatheRex™ Cell Harvest and Liquid Handling Pump

GatheRex™ Cell Harvest and Liquid Handling Pump

GatheRex with G-Rex500M-CS

Harvest your final cell product in minimal volumes.

The GatheRex maximizes cell harvest yields and minimizes product loss. Designed for use in cell manufacturing under cGMP conditions, GatheRex is the perfect partner for G-Rex closed-system bioreactors.

GatheRex Liquid Handing and Cell Harvest System

Cell harvest without centrifugation.

Complicated cell harvesting protocols are a thing of the past. GatheRex automates the gentle removal of excess media from G-Rex bioreactors, leaving your cell product resting undisturbed in a nutrient and oxygen rich environment. Then, use the G-Rex to harvest your concentrated cells without the need for centrifugation.


How Does GatheRex Work?

GatheRex connects to the sterile vent filter on the G-Rex, pushing positive, sterile air pressure into the bioreactor. When pressurized, excess media, or a cell fraction is forced through the G-Rex tubing assembly and into a collection receptacle. GatheRex can reduce liquid volumes by 90% within 5 minutes.

“Wilson Wolf has had back and forth communication with the scientific community and a lot of the design actually has been from feedback on the device. I think that’s part of the reason the devices work so well…they have taken at heart a lot of the feedback.”

Analytical Tools to Evaluate CAR-T Cell Signaling & Activation App Note

Chimeric antigen receptor (CAR)-T cell therapy is a revolutionary new pillar in cancer treatment with success in treating specific subsets of B cell leukemia, lymphoma, and multiple myeloma.  Much attention is focused on expanding CAR-T cell therapy to other hematologic malignancies and solid tumors. Central to engineering effective CAR-T cell therapies is a detailed understanding of the signaling cascades that regulate CAR-T cells, including trafficking and tumor infiltration, preventing antigen escape, resisting immunosuppressive responses, and ameliorating potentially fatal toxicity. Detailed characterization of extracellular, membrane-bound, and intracellular signaling molecules is required, often with limited and complex sample types.
