Qube and QPatch can run succesfull experiments on stem cells, however be aware that the ion channel expression changes with the maturity of the iPSC cells and iPSC cells often contains a mix of cells. We expect that to be improved going forward.


We recommend using QPatch for stem cell work since you can obtain good gigaseals and high success rates in physiological solutions, wherease you need flouride on Qube. Alternative platform on the market use seal enhancing agents to obtain decent seals. QPatch can run experiments on iPSC stem cells and primary cells with a gigaseal rate above 95% and a success rate up to 70% (Franz et al. 2017).


Optimal cell culture procedures are key to obtain high quality experiments and the success rate is dependent of the cell density. The lower limit for the cell density varies between cells provided from different vendors and even from batch to batch.
