<p>DoubleQuick DNA Electrophoresis Buffer is a tank buffer used in electrophoresis of DNA on agarose gels. The advantage here is that the electrophoreis takes only 10 minutes and the DNA extraction rate is 3 times higher than when TAE or TBE buffers are used. It also generates lower heat.</p>Couleur et forme :Liquid, Colourless6x DNA Loading Dye
<p>6x Gel Loading Dye is a pre-mixed loading buffer with two tracking dyes for agarose and non-denaturing poylacrylamide gel electrophoresis. EDTA is included to chelate magnesium (up to 10 mM) in enzymatic reactions, thereby stopping the reaction. Bromophenol blue and xylene cyanol are the standard tracking dye for electrophoresis.</p>Couleur et forme :Liquid, Blue6x Blue Loading Dye
<p>6X Blue Loading Dye is a pre-mixed loading buffer with a single tracking dye for agarose and non-denaturing poylacrylamide gel electrophoresis. EDTA is included to chelate magnesium (up to 10 mM) in enzymatic reactions, thereby stopping the reaction. Bromophenol Blue is the standard tracking dye for electrophoresis.</p>Couleur et forme :Liquid, Blue6x Orange Loading Dye
<p>6x Gel Loading Dye is a pre-mixed loading buffer with two tracking dyes for agarose and non-denaturing poylacrylamide gel electrophoresis. EDTA is included to chelate magnesium (up to 10 mM) in enzymatic reactions, thereby stopping the reaction. Xylene cyanol and Orange G are the standard tracking dyes for electrophoresis.</p>Couleur et forme :Liquid, Dark GreenSodium cacodylate trihydrate
