Are you assaying the transfections or trying to isolate the DNA 
following transfection..?

Anyhow, using standard calcium phosphate technique I have transfected 
into a whole mess of primary cultures..including chick and rat primary 
fibroblasts. Maybe the problem with mouse is a species/tissue thing. Are 
you changing the culture media prior to transfection? Is it defined 
media? If defined..maybe you should pre-incubate the media for 24 hours 
before use (a trick that makes some cultures transfect!!! dont ask me 

good luck
