I hate fluorescent lighting.

That's a fluorescent tube refined.

But here it is. It's fluorescent.

I must replace that fluorescent lamp.

Solutions of the dye, therefore, are blue.

Filament notching describes another phenomenon that limits the life of lamps.

In 1878, a German chemist named a.

And now, boom, the tumor labels itself and it gets fluorescent.

Dye Bromophenol blue is also used as a dye.

It is used as a pH indicator in applications such as growth mediums for microorganisms and titrations.

In some cases, a pigment can be manufactured from a dye by precipitating a soluble dye with a metallic salt.

Tyrian purple is a dull purple dye that is secreted by a common Mediterranean snail.

Development of the blot is then stopped by washing away the soluble dye.

Cochineal is a product of an insect that lives off these cacti.

The cell wall of bacteria is also distinct from that of Archaea, which do not contain peptidoglycan.

At neutral pH, the dye absorbs red light most strongly and transmits blue light.

In the subtractive model, adding white to a color, whether by using less colorant or by mixing in a reflective white pigment such as zinc oxide, does not change the color's hue but does reduce its saturation.

A dye is a colored substance that has an affinity to the to which it is being applied.

And we've stained these cultures with a green florescent dye so that we can look at these proteins that form these chains.

Examples of procedures that use oligonucleotides include DNA microarrays, Southern blots, ASO analysis, fluorescent in situ hybridization (FISH), and the synthesis of artificial genes.

A colorant can act as either a pigment or a dye depending on the vehicle involved.

We take that tissue, we purify the RNA out of it using some basic technology, and then we put a florescent tag on it.

The proposed mechanism was either direct excitation of the dye molecules or excitation of electrons.

Often the light will turn pink (see Loss of mercury) with black burns on the ends of the lamp due to sputtering of emission mix (see below).

In 1856 William Henry Perkin, while trying to manufacture quinine, accidentally manufactured the organic dye now known as Perkin's mauve.

Usually acetic acid is added to the dyebath to help the uptake of the dye onto the fiber.

At low pH, the dye absorbs ultraviolet and blue light most strongly and appears yellow in solution.

The epicenter of the latter was in the sea about to the east of Kythira, with a focus at a depth of approximately .

Perkin's discovery is the foundation of the dye synthesis industry, one of the earliest successful chemical industries.

Some bacteria, after staining with the Gram stain, yield a gram variable pattern a mix of pink and purple cells are seen.

Martin Chalfie figured out how to use GFP as a fluorescent marker of genes inserted into other cells or organisms.

Studies indicate that the luciferin of many krill species is a fluorescent tetrapyrrole similar but not identical to dinoflagellate luciferin and that the krill probably do not produce this substance themselves but acquire it as part of their diet, which contains dinoflagellates.

However, all such devices are classified as lasers based on their method of producing light, i.e., stimulated emission.

Attachment to the fiber is attributed, at least partly, to salt formation between anionic groups in the dyes and cationic groups in the fiber.

About the time pretzel M M's came out, the M M's wrapper designs in the U.S. were redone, from the old design, used from 2004 early 2010.

This converts the soluble dye into an insoluble form of a different color that precipitates next to the enzyme and thereby stains the membrane.

Biotechnology In 1961, Osamu Shimomura extracted green fluorescent protein (GFP) and another bioluminescent protein, called aequorin, from the large and abundant hydromedusa Aequorea victoria , while studying photoproteins that cause bioluminescence in this species.

The orange dye was particularly unstable and tended to turn red after a while, so in the mid 17th century, red was made the official color.

A distinction is usually made between a pigment, which is insoluble in its vehicle (resulting in a suspension), and a dye, which either is itself a liquid or is soluble in its vehicle (resulting in a solution).

One critic notes that Barton's fixation on the stain across the ceiling of his hotel room matches the protagonist's behavior in Flannery O'Connor's short story The Enduring Chill .

Even today indigo is very much appreciated as a color for the summer Kimono Yukata, as this traditional clothing recalls Nature and the blue sea.

If a physician suspects a case of Williams syndrome, the diagnosis is confirmed using one of two possible genetic tests micro array analysis or the fluorescent in situ hybridization (FISH) test.

And it was very peculiar, because it was dark out, but she was back lit with florescent lighting, and she was very much onstage, and I couldn't figure out why she was doing it.

One way to do this is to replace the wild type gene with a 'fusion' gene, which is a juxtaposition of the wild type gene with a reporting element such as green fluorescent protein (GFP) that will allow easy visualization of the products of the genetic modification.

A useful technique for assessing cellular localization uses genetic engineering to express in a cell a fusion protein or chimera consisting of the natural protein of interest linked to a reporter such as green fluorescent protein (GFP).
