Nile Blue Staining
Nile blue is used for histological staining of biological preparations. It highlights the distinction between neutral lipids (triglycerides, cholesteryl esters, steroids) which are stained pink and acids (fatty acids, chromolipids, phospholipids) which are stained blue.
The Nile blue staining, according to Kleeberg, uses the following chemicals:
- Nile Blue A
- 1% acetic acid
- Glycerol or glycerol gelatin

Famous quotes containing the words nile and/or blue:
“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)
“The blue we bathe in is the blue we breathe. The blue we breathe, I fear, is what we want from life and only find in fiction. For the voyeur, fiction is what’s called going all the way.”
—William Gass (b. 1924)
