How to seed adherent cells evenly in 150mm dishes? - (Jul/23/2007 )
How much medium do you use in a 150mm plate?
I use 20ml.
When transferring medium, I always use serological pipette, I don't "pour".
I'm afraid pour will cause cantamination. I never dare to try it.
Actually I handle at least 10 150mm plates at the same time:
I use them to culture AAV293 cells and produce AAV.
What do you use 150mm plates for?
I like the simplicity of this method, particularly when I work with multiple plates.
I have been using it for many years with little problem. Believe or not, accidentally touching the tip of a pippet and use it unknowingly afterwards could be the single the most frequent source of contamination. This method in principle can reduce the chance of getting contaminated. I usally spead some 75% EtOH on the outside of the bottle after use. I really have had no problem with this method.
I did adv production with 293 cells before. The medium turn yellow after 48 hrs. So I prefer adding more medium than less.
