Protocol needed stain Cos cells for DNA,RNA

[Mary P. Remington]

We have transfected by electroporation, Cos-1 cells with an expression 
vector containing a retroviral gene.  Is there a way to probe cells on a 
slide for DNA and RNA.  We want to determine if the cells have been 
transfected and if there is RNA being made from the construct.  I know we 
could isolate RNA and DNA and do Southerns and NOrtherns but, we are 
looking for something quicker and in vitro.  Thanks for any help.
