ethanol treatment vs. plasmid loss

I have an mAb that recognizes an intracellular epitope of a T cell
membrane glycoprotein. I want to clone the protein this mAb recognizes
by transfecting a T cell cDNA library into NIH 3T3 cells and screening by
flow cytommetry (FACS) with our FITC-labeled mAb. The problem I am
concerned about is that to screen with my mAb we have to first
permeabilize the transfected cells with 70% ethanol. I am worried that a
successfully transfected plasmid would be lost after ethanol treatment.
Am I wrong to assume the loss of a plasmid after 70% ethanol treatment or
is this something that is likely to occur.
