Loading Buffer II

Loading buffer II (6x) is used for DNA samples dissolved in water or TE-buffer.
Loading buffer II increases the density of the sample and adds dye for simplifying the loading process for acrylamide and agarose gels. In 1 % agarose gels, bromphenol blue migrates with 300 bp linear double-stranded DNA fragment, while xylene cyanol FF migrates at approximately the same rate as linear doublestranded DNA fragments of 4 kb length.
