Is anyone here culturing H9C2 cells? My H9C2 cells growth rate is very slow and I am not sure what is the problem with this. I am using DMEM with 10% FBS and 1% sodium pyruvate and Passage 24 of H9C2 cells. Some info from this website say that we have to do a clone selection by using a 96 well plates. Can anyone share how to do this?
