Description
D-Luciferin Firefly, potassium salt is a bioluminescent substrate with CAS number 115144-35-9 and empirical formula C₁₁H₇KN₂O₃S₂. It has a molar mass of 318,41 g/mol. This potassium salt form of D-luciferin, from manufacturer Carl ROTH, is the classic light-emitting substrate of firefly luciferase and is applied in ATP assays, reporter-gene studies, in vivo imaging workflows, and cell-viability or kinetic luminescence measurements. The salt improves aqueous handling for buffer preparation and high-sensitivity detection on plate readers and imaging systems. Biochemists and molecular biologists rely on well-defined luciferin reagents to obtain reproducible photon output in luciferase-coupled experiments. Clear CAS and molecular identity aid compliance documentation and batch traceability in research, screening, and quality laboratories working with bioluminescence platforms.

Questions about D-Luciferin Firefly, potassium salt, 250 mg
What is this article?
D-Luciferin Firefly, potassium salt, 250 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.
