How dangerous is a membrane impermeable dye?? Unless it can resurrect dead
epithelial cells, it should not have access to the DNA of living cells, and
thus shouldn't be much of a safety hazard.

We always wipe everything down with ethanol, but I've yet to see data
showing membrane impermeable DNA intercalating dyes cause problems for
living cells. I think the MSDS claims are based on a general fear of
anything that has the word "DNA" in it.

Anyone have data to contradict this??
