The EZ-Flask (“easy-flask”) is a new cell culture flask tailored for very easy in vitro monoclonal antibody production from hybridomas. Higher yields are obtained from EZ-Flask thanks to a gas exchange membrane. The design also means that no passaging or tricky routine manipulations are needed – just fill with media, inoculate, wait a couple of weeks and then harvest 1 litre of high titre mAb.
1) Simple and easy – high yields with no passaging required !
Just fill and inoculate. No need for cell passaging. In 2 to 4 weeks the process is complete and with a good clone you can harvest yields up to 150 mg in 1 Litre.
2) Economical monoclonal antibody production
The simple design concept makes this is a very economical bioreactor especially when compared to laborious flasks where cell passaging is needed. It can also save a lot of valuable incubator space that might otherwise be wasted on T-Flasks. In terms of monoclonal antibody productivity, 1 EZ-Flask is equivalent to 20 – 100x T-175 flasks depending on the clone. Some users report yields of up to 150mg of mAb after 30 days of culture.
3) How does it work?
After inoculation hybridomas will quickly proliferate to form a dense layer above the gas permeable membrane at the base of the cell culture flask.
Very well-oxygenated and nourished at all times, the cells are thus much more productive than in T-flasks or roller bottles.
Stressed hybridomas, that increase their monoclonal antibody production following the log growth phase can be fully exploited in this system.
Other suspension cell types
All types of suspension cells can be expanded to high numbers without passaging in the EZ-Flask, e.g. CHO, Jurkat, B-cells, THP1.
EZ-Flask and G-Rex Plates are particularly well suited for the development of suspension CHO cell lines.
Use G-Rex® Plates to optimize culture conditions for EZ-Flask
Each well of a G-Rex Plate can be used as a scaled-down version of an EZ Flask.
Each well essentially behaves like a “mini bioreactor”. These plates therefore provide a fast and convenient way to optimize parameters such as seeding density (cells/cm2 membrane), media, duration, etc.
G-Rex Plates are very convenient for developing monoclonal antibodies and for hybridoma clone selection.
