Flavoprotein

The first mention of a flavoprotein in the scientific literature dates back to 1879, when the work on the composition of cow’s milk resulted in the isolation of a bright-yellow pigment, that we now know as flavin, but termed lactochrome at the time.

Francis Dennis Ramsay

However, as the paint is not commercially available, the artist must mix his own colours using pigment powders, oil, varnish, egg yolk and a preservative; uniquely, Ramsay discovered that Scotch whisky is an excellent preservative for the egg in the oil tempera mix!

Plasmodium pelaezi

Schizonts are mostly round with a single mass of pigment and render the host cell nuclei spherical.

Richard A. Jorgensen

His and Carolyn Napoli's observations of pigment gene 'cosuppression' in Petunia flowers are examples of post transcriptional gene silencing that predated the discovery of RNA interference (RNAi) and contributed to the current understanding of the commonality of RNA-mediated gene silencing in eukaryotes.

Through colour render

Through colour render is a sand/cement/lime based render that is made from White Portland cement (WOPC) and added pigment to produce a coloured effect that is throughout the body of the material.

Tiwest Joint Venture

Most synthetic rutile from Chandala was then trucked to Kwinana, 30 km south of Perth, to the Tiwest-owned pigment plant, which produces titanium dioxide aka TiO2.
