ClearBand 6x DNA Loading Dye Green is a pre-mixed buffer, which can be used for loading DNA markers and samples into the wells of agarose and non-denaturing polyacrylamide gels.It contains two tracking dyes, Xylene Cyanol FF and Orange G, for visualization of DNA migration on the gels. Orange G runs around 50 bp fragment in agarose gels, which provides much better tracking of DNA before it runs off the gel. Besides, Orange G does not result in formation of a dark shadow on the gel as Bromophenol Blue does, which runs around 400 bp fragment precisely where PCR fragments are likely to be.
