Description
100 bp Fluorescent DNA Ladder is a ready-to-use, pre-dyed molecular weight marker for sizing DNA fragments during horizontal agarose gel electrophoresis. Supplied as a 500 µl plastic unit, it is intended for the separation of nucleic acids in agarose gels and supports direct loading without separate dye addition. The fluorescent, pre-stained format helps laboratories visualise reference bands alongside sample DNA under standard imaging setups used in molecular biology. Physical data include a density of approximately 1 g/cm³ and a boiling point of 100 °C. This ladder is suited to routine nucleic acid analysis where clear 100 bp-range reference patterns are required in agarose gels. The plastic pack presentation simplifies handling within electrophoresis reagent stocks. From manufacturer Carl ROTH, the product serves applications in horizontal electrophoresis workflows focused on DNA fragment size estimation. Packed unit weight is 0,293 kg. Use it as a convenient fluorescent DNA size standard in research and analytical gel electrophoresis of nucleic acids.

Questions about 100 bp Fluorescent DNA Ladder
What is this article?
100 bp 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?
