Description
6-Carboxytetramethylrhodamine succinimidyl ester is a fluorescent labelling reagent with CAS number 150810-69-8 and the empirical formula C₂₉H₂₅N₃O₇. The molar mass is 527,52 g/mol. This activated N-hydroxysuccinimide ester of the 6-carboxy isomer of tetramethylrhodamine is intended for covalent conjugation to primary amines on proteins, peptides and other biomolecules. The rhodamine fluorophore provides strong visible emission commonly exploited in multiplex labelling schemes. Material from manufacturer Carl ROTH is suitable for research laboratories that require a defined amine-reactive dye for bioconjugation chemistry. Careful control of reaction pH and stoichiometry allows efficient incorporation of the dye while preserving biological activity of the target molecule. The compact pack size is practical for method development, small-scale labelling campaigns and quality-control applications in biochemical and molecular-biology settings.

Questions about 6-Carboxytetramethylrhodamine succinimid, yl ester, 50 mg
What is this article?
6-Carboxytetramethylrhodamine succinimid, yl ester, 50 mg 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 Lab chemicals.
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.
