  • What is gel loading dye?
  • Gel Loading Dye, Orange (6X) is a pre-mixed loading buffer with a tracking dye for agarose and non-denaturing polyacrylamide gel electrophoresis. This solution contains SDS, which often results in sharper bands, as some restriction enzymes are known to remain bound to their DNA substrates following cleavage.
  • Does Orange G appear in gel photos?
  • Orange G will not appear in gel photographs, and runs ahead of all but the smallest restriction fragments. Orange G migrates at approximately 50 bp on a standard 1% TBE agarose gel. This product is packaged as 4x1 ml vials. Use 5 µl of Gel Loading Dye, Orange (6X) per 25 µl reaction, or 10 µl per 50 µl reaction. Mix well before loading gel.
  • What is orange G used for?
  • It is widely used as a tracking dye for nucleic acid gel electrophoresis to track DNA front in agarose gels. Typically runs at 50bp in up to 2.5% agarose. Orange G has been used as a DNA gel loading dye. Orange G is a tracking dye used in nucleic acid electrophoresis to track DNA front in agarose gels.
  • What dyes can be used to color agarose gels?
  • Bromophenol blue and xylene cyanol can also be used for this purpose. (However, the apparent "size" of all these dyes varies according to the concentration of agarose in the gel and the buffer system used, so one should look up the appropriate reference before using the dyes to determine how far a gel has run.)
