I need a little help from you dear readers. I need to know the purpose behind culturing cells in a serum free medium. I'm thinking its to control for things like growth factors that are present in serum, but i'm not sure. I have so many other things to find, learn and figure out that I'm hoping you can save me on this one.
pretty please with sugar on top? I'll even tell you how I made Src my bitch.
