Beschrijving
Nijlerood is een extra zuivere lipofiele fenoxazinekleurstof die wordt gebruikt bij biologische kleuring en fluorescentiegerelateerde laboratoriumtoepassingen. Het wordt gedefinieerd door CAS-nummer 7385-67-3, de brutoformule C₂₀H₁₈N₂O₂ en een molaire massa van 318,38 g/mol. Nijlerood wordt veelvuldig toegepast in de microscopie, celbiologie en analytische workflows waar een selectieve lipiden-gevoelige fluorofoor is vereist. De extra zuivere kwaliteit ondersteunt consistente prestaties in onderzoeks- en onderwijslaboratoria die werken met kleurstoffen voor biologische toepassingen. Dit reagens is bij fabrikant Carl ROTH verkrijgbaar in een compacte gramhoeveelheid, geschikt voor methodeontwikkeling en routinematige kleuring. Bereid oplossingen en hanteer de vaste stof volgens goede laboratoriumpraktijken en raadpleeg het veiligheidsinformatieblad voor het eerste gebruik.
Dit artikel hoort bij Fluorescente kleurstoffen & labels, in Kleurstoffen, vloeistoffen & indicatoren.

Questions about Nijlrood, extra puur, 1 g, glas
What is this article?
Nijlrood, extra puur, 1 g, glas is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Fluorescent dyes & labels, inside Dyes, stains & indicators, in Chemicaliën.
A fluorescent dye absorbs at one wavelength and emits at a longer one. As a label it is attached to a protein, a nucleic acid or a cell. Excitation and emission maxima, and the reactive group if it must conjugate, are the specification. The colour name does not tell you the wavelengths.
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.
Which category should I open next?
The category is Dyes, stains & indicators. The sub-category is Fluorescent dyes & labels. The catalogue is Chemicaliën.
