G-Rex Hybridoma Culture Plates
Generate useful amounts of monoclonal antibody from each well
No passaging required
G-Rex culture plates enable the expansion of hybridomas to very high numbers without the need for passaging.
Each 35ml well of a G-Rex 6 Plate acts as a mini-bioreactor yielding 3 – 6 x more monoclonal antibody than a T-175 flask. See example data below.
Gas permeable base membrane
A gas-permeable silicone membrane at the base of each well ensures cells are oxygenated despite the deep well design.
The only limitation on cell proliferation is the volume and type of media. Exponential growth takes place over a period of days with minimal user intervention.
Ideal for comparing hybridoma clones
Inoculate G-Rex 6 with 1.25 million cells / well …and 10 days later, with just one media exchange, each well can yield 200 to 400 million cells.
“We tested your G-Rex 6 well Plates with very good results. We used newly etablished monoclonal cell lines to generate the first amounts of purified antibodies”
We tried two rat mAbs, #IBL-11 (against an undefined mouse lymphoid stromal marker) and #IBL-12 against mouse MARCO antigen, both developed in our lab. Considering the speed for achieving several mgs of each, I am very satisfied with the performance of G-rex, and the ease of operation.
We could clearly collect and re-initiate the growth by removing weekly (a) 30 ml of supernatant, adding fresh, and (b) three days later collecting 32 ml (out of 35 total) of another spent medium with cells (so we had twice-a-week SN harvest) for three weeks.
I have just performed our experiments and I have to inform you that I’ve obtained very good amounts of antibodies from the G-Rex6. Since, I got a much larger amount from this than from my normal protocol I couldn’t quantify it yet and I will have to dilute it next time. For now we would like to get 20 EZ flasks and 6 G-Rex6 well plates since we are starting a new project for antibody production. We would like to implement these production systems right away.
