  2. Xylene cyanol - Wikipedia

    en.wikipedia.org/wiki/Xylene_cyanol

    Xylene cyanol can be used as an electrophoretic color marker, or tracking dye, to monitor the process of agarose gel electrophoresis and polyacrylamide gel electrophoresis. Bromophenol blue and orange G can also be used for this purpose. Once mixed with the sample, the concentration of xylene cyanol is typically about 0.005% to 0.03%.

  3. Electrophoretic color marker - Wikipedia

    en.wikipedia.org/wiki/Electrophoretic_color_marker

    Xylene and bromophenol blue are the most commonly used dyes. [ citation needed ] Generally speaking, Orange G migrates faster than bromophenol blue, which migrates faster than xylene cyanol, but the apparent "sizes" of these dyes (compared to DNA molecules) varies with the concentration of agarose and the buffer system used.

  4. Bromophenol blue - Wikipedia

    en.wikipedia.org/wiki/Bromophenol_blue

    Bromophenol is also used as a colour marker to monitor the process of agarose gel electrophoresis and polyacrylamide gel electrophoresis.Since bromophenol blue carries a slight negative charge at moderate pH, it will migrate in the same direction as DNA or protein in a gel; the rate at which it migrates varies according to gel density and buffer composition, but in a typical 1% agarose gel in ...

  5. Agarose gel electrophoresis - Wikipedia

    en.wikipedia.org/wiki/Agarose_gel_electrophoresis

    Since DNA is not visible in natural light, the progress of the electrophoresis is monitored using colored dyes. Xylene cyanol (light blue color) comigrates large DNA fragments, while Bromophenol blue (dark blue) comigrates with the smaller fragments. Less commonly used dyes include Cresol Red and Orange G which

  6. Gel electrophoresis of nucleic acids - Wikipedia

    en.wikipedia.org/wiki/Gel_electrophoresis_of...

    Xylene cyanol and Bromophenol blue are common dyes found in loading buffers; they run about the same speed as DNA fragments that are 5000 bp and 300 bp in length respectively, but the precise position varies with percentage of the gel.

    It's flu season right now, and the U.S. is in the midst of a wave that's straining hospitals.But not all influenza is the same. There are some notable differences between flu A and flu B strains.

  8. Cresol Red - Wikipedia

    en.wikipedia.org/wiki/Cresol_Red

    Cresol red can also be used as an electrophoretic color marker to monitor the process of agarose gel electrophoresis and polyacrylamide gel electrophoresis.In a 1% agarose gel, it runs approximately at the size of a 125 base pair (bp) DNA molecule (it depends on the concentration of buffer and other component).
