Hello, I'm going to culture HepG2 cells soon, I studied many research articles but half of them culture HepG2 in 10% FBS in DMEM and rest of them used 10% FCS in DMEM. I was wondering as HepG2 is the cancer cell line FCS would be the better option to choose over FBS in terms of avoiding contamination. Can please somebody help me out from this dilemma? Which one should be the best FCS or FBS?
