surely the problem with endotoxins is not that they inhibit transfection
per se, but rather that they kill the transfected cells, thereby reducing
apparent transfection efficiency?  So any cell line will exhibit this
effect if there's enough LPS knocking around?

So Stratagene is working on an endotoxin-free maxi-prep kit, now?  :) 
What are you using?
