The Coomassie Blue G250 dye used to bind to the proteins in the original Bradford method readily binds to arginine and lysine groups of proteins. This is a disadvantage because the preference of the dye to bind to these amino acids can result in a varied response of the assay between different proteins.
Aniline Blue WS, also called aniline blue, diphenylamine blue, China blue, or Soluble blue, is a mixture of methyl blue and water blue. It may also be either one of them. [ 1 ] It is a soluble dye used as a biological dye, [ 2 ] in fluorescence microscopy , appearing a yellow-green colour after excitation with violet light. [ 3 ]
2,6-Dichlorophenolindophenol (DCPIP, DCIP or DPIP) is a chemical compound used as a redox dye. When oxidized, DCPIP is blue with a maximal absorption at 600 nm; when reduced, DCPIP is colorless. DCPIP can be used to measure the rate of photosynthesis. It is part of the Hill reagents family. When exposed to light in a photosynthetic system, the ...
Hyperspectral imaging (HSI) devices for spatial scanning obtain slit spectra by projecting a strip of the scene onto a slit and dispersing the slit image with a prism or a grating. These systems have the drawback of having the image analyzed per lines (with a push broom scanner ) and also having some mechanical parts integrated into the optical ...
The H&E staining procedure is the principal stain in histology [3] [7] [2] [5] in part because it can be done quickly, [7] is not expensive, and stains tissues in such a way that a considerable amount of microscopic anatomy [9] [10] is revealed, [7] [5] [4] and can be used to diagnose a wide range of histopathologic conditions. [8]
As a blue dye (with alum as a mordant), the initial results were not as lightfast as those produced using indigo. [ 7 ] [ 9 ] In reaction to this perceived inferiority of the quality of the blue colour produced with haematoxylin, its use to dye fabric was barred in England from 1581 to 1662.
ICE’s recently revealed “Cryptocurrency Intelligence Program” is deployed in all crypto-facing Homeland Security investigations, says the agent whose unit built the tool.
Copper phthalocyanine ("phthalo blue") is a synthetic blue pigment frequently used in paints, inks, and dyes. It is highly valued for its superior properties such as light fastness, tinting strength, covering power and resistance to the effects of alkalis and acids. It has the appearance of a blue powder, insoluble in most solvents including ...
