I agree that there's not much out there to justify the excessive cautions
that are taken with EtBr, but I've seen for myself that it enters cells. I
used to experiment with EtBr on L-929 in the early days, and the pellet of
treated cell nuclei was definitely coloured red by EtBr.

By the way, this topic is on a regular cycle in this forum!
