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.

Famous quotes containing the words nile, blue and/or dna:
“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;”
—Thomas Lovell Beddoes (1803–1849)
“That air would disappear from the whole earth in time, perhaps; but long after his day. He did not know just when it had become so necessary to him, but he had come back to die in exile for the sake of it. Something soft and wild and free, something that whispered to the ear on the pillow, lightened the heart, softly, softly picked the lock, slid the bolts, and released the prisoned spirit of man into the wind, into the blue and gold, into the morning, into the morning!”
—Willa Cather (1873–1947)
“Here [in London, history] ... seemed the very fabric of things, as if the city were a single growth of stone and brick, uncounted strata of message and meaning, age upon age, generated over the centuries to the dictates of some now all-but-unreadable DNA of commerce and empire.”
—William Gibson (b. 1948)
