Description
25 kb Fluorescent DNA Ladder is a ready-to-use, pre-dyed molecular weight marker designed for DNA fragment sizing in horizontal agarose gel electrophoresis. Offered as a 500 µl plastic unit, it supports the separation of nucleic acids in agarose gels and is prepared for direct gel loading without a separate staining step. Its fluorescent pre-dyed format assists visualisation of reference bands under imaging conditions common in molecular biology laboratories. Key physical characteristics are a density of approximately 1 g/cm³ and a boiling point of 100 °C. The ladder is appropriate for agarose electrophoresis workflows that require a fluorescent size standard in the 25 kb range. Plastic packaging keeps the reagent convenient to handle within electrophoresis reagent sets. From manufacturer Carl ROTH, it fits applications centred on horizontal electrophoresis and nucleic acid separation in agarose gels. Packed unit weight is 0,293 kg. Choose this fluorescent DNA ladder for routine research and analytical sizing of larger DNA fragments on agarose gels.

Questions about 25 kb Fluorescent DNA Ladder
What is this article?
25 kb Fluorescent DNA Ladder 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.
Which category should I open next?
