No, but I do know the Plus reagent inhibits the phospholipase C assay as it
may disrupt the membrane more than just Lipfectamaine...

My suggestion woud be to try the lippofectamine alone and a sham control
with just the plus reagent and compare the background of all three.  Also
what cells are you using?  Some, especially of lung orign, are noted for
horrible background fluorescence.

Hope this helps,
