6X BX/ Loading buffer
For visual Tracking of DNA Migration during Electrophoresis
6X BX/Loading Buffer is used as a loading dye for visual tracking of DNA migration during electrophoresis. It incorporates Bromophenol blue and Xylene Cyanol FF as tracking dye. Bromophenol blue migrates fast in the agarose gel and corresponds to the migration of a 300 – 500 bp long DNA fragment in a 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.
EDTA is included in the solution to protect the sample from nuclease degradation. Glycerol is added to provide high density to the solution. Due to its high density, the sample settles at the bottom of the well. It also helps DNA samples to be confined in the well without diffusing out from it.
