6X OX/Loading Buffer
For visual Tracking of DNA Migration during Electrophoresis
6X OX/Loading Buffer is used as a loading dye for visual tracking of DNA migration during electrophoresis. It incorporates Orange G and Xylene Cyanol FF as tracking dye. Orange G migrates comparatively very fast and corresponds to the migration of a 50 bp long DNA fragment in 1% agarose gel. Xylene cyanol FF migrates comparatively slower and corresponds to the migration of a 4,000 – 5,000 bp long DNA fragment in a 1% agarose gel.
The EDTA is included in the solution to protect samples from nuclease degradation. Glycerol is added to provide high density to the solution. Due to its high density, sample settles at the bottom of the well. It also helps DNA samples to be confined in the well without diffusing out from it.
