Nile Blue in DNA Electrophoresis
Nile blue is also apparently used in a variety of commercial DNA staining formulations used for DNA electrophoresis. As it does not require UV trans-illumination in order to be visualised in an agarose gel as with ethidium bromide, it can be used to observe DNA as it is separated and also as a dye to aid in gel-extraction of DNA fragments without incurring damage by UV-irradiation.

“Hard by the lilied Nile I saw
A duskish river dragon stretched along.
The brown habergeon of his limbs enamelled
With sanguine alamandines and rainy pearl:
And on his back there lay a young one sleeping,
No bigger than a mouse;”

—William Gibson (b. 1948)
