How do you account for cell confluency when performing knock down studies in differentiated vs undifferentiated cells?

I am trying to knock down a gene of interest using siRNA in SH-SY5Y cells. But the amount of siRNA I use is mostly based on the well surface area etc. I use 50pmol/well in a 6-well plate. So is it...
