Questions about 5-Carboxytetramethylrhodamine-PEG3-Azide, min. 90 %, 5 mg, plastique
What is this article?
5-Carboxytetramethylrhodamine-PEG3-Azide, min. 90 %, 5 mg, plastique is the article on this page. Luminix Health distributes baseclick for laboratory use. It sits in Fluorescent dyes & labels, inside Dyes, stains & indicators, in Produits chimiques de laboratoire et industriels.
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.
