Questions about Nile blue A (C.I. 51180), 80 %, 10 g, verre
What is this article?
Nile blue A (C.I. 51180), 80 %, 10 g, verre is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Colorants & solutions de coloration pour microscopie, inside Colorants, colorations & indicateurs, in Produits chimiques.
A microscopy stain binds a structure so it can be seen: haematoxylin on nuclei, eosin on cytoplasm, Gram reagents on a bacterial wall. A ready solution and a dry dye to be dissolved are different articles. The method names the stain. A substitute dye is a different method.
A dye or a stain binds, or changes colour, so that something invisible becomes visible. An indicator changes at a pH or a redox point. A fluorescent dye absorbs one wavelength and emits another, which is how a microscope or a plate reader picks it out. The excitation and emission, or the transition interval, are the specification. The colour name on the label is not. Structures are on PubChem under IUPAC names. Methods are in the PubMed literature.
