We ordered MCF10A cell line from ATCC and seed the cells in suggested conditions except adding cholera toxin and pen/strep. We made three stocks in this conditions but then suddenly our cells started to die and we cant stop it.

Our conditions are NOW : MEBM medium + MEGM kit + 100  ng/ml cholera toxin.

We tried to remove cholera toxin but the results are same.

Can anybody tell me where we are wrong?

Thank you.
