Description
50 bp Fluorescent DNA Ladder is a ready-to-use, pre-dyed molecular-weight marker for nucleic-acid separation on agarose gels. The fluorescent formulation is designed for horizontal electrophoresis workflows in which clear size reference bands are required during analysis of DNA fragments. Supplied in a 500 µl plastic pack, the ladder is prepared for direct loading, reducing preparation steps at the bench. Physical characteristics include a density of approximately 1 g/cm³ and a boiling point of 100 °C. This electrophoresis reagent from manufacturer Carl ROTH supports routine separation of nucleic acids in agarose gel systems used in molecular biology, cloning verification and related laboratory applications. The pre-dyed, ready-to-use format helps standardise fragment sizing across runs and simplifies comparison of experimental samples against a consistent 50 bp reference ladder. It is intended for laboratories that need a convenient fluorescent DNA size standard for horizontal agarose electrophoresis and everyday nucleic-acid analysis.
This article is part of Fluorescent dyes & labels, in Dyes, stains & indicators.

Questions about 50 bp Fluorescent DNA Ladder, ready-to-use, pre-dyed, 500 µl
What is this article?
50 bp Fluorescent DNA Ladder, ready-to-use, pre-dyed, 500 µl 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 Produits chimiques.
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.
