- noun A coal-tar color used in dyeing.
- noun The name is applied to two basic dye-stuffs of the diphenyl-methane type. The older was discovered in 1883; the suffixes O, I, and II indicate various degrees of its purity and strength. The other, known as auramine G, was discovered in 1892, and differs from the former in that it contains a tolyl in place of a phenyl group.

Sorry, no etymologies found.
By adding the dye in portions this difficulty is overcome and more level shades are obtained; it is met with in all cases of jigger dyeing, but it is most common in dyeing cotton or wool with basic dyes like magenta, auramine, methyl violet or brilliant green, and in dyeing wool with acid dyes like acid green, formyl violets, azo scarlet, or acid yellow.
The chemical composition of the wool fibre is evidently of a most complicated nature; judging from its behaviour in dyeing it is evident that it may contain two bodies, one of a basic character which enables it to combine with the azo and acid series of dyes, the other possessing acid characters enabling it to combine with the basic dyes of the magenta and auramine type.
Hands-on time does not, for example, include time while smears are being passively stained (eg auramine staining for FM) but does if the stain needs to be heated periodically (eg carbol fuchsin staining for ZN).

Through implementing new policy recommendations and LED-based fluorescence microscopy the current laboratory staff complement could investigate the same number of patients, examining auramine-stained smears to an extent that is equivalent to a 10 minutes ZN smear examination.
An "excitation" wavelength is emitted by the light source -- a blue light-emitting diode (LED) on the opposite end of the device from the cell phone -- and absorbed by the auramine dye in the spit sample, which fluoresces green to illuminate TB bacteria.
The efficiency of infection was determined by auramine rhodamine stain and was regularly in the range of 30%, with an average of 1.1 bacteria per infected cell.
