M9081 6× Gel Loading Dye, SDS+

Product Introduction

6× Gel Loading Dye, SDS+ is a pre-mixed loading buffer with two tracking dyes for agarose and non-denaturing polyacrylamide gel electrophoresis. This solution contains SDS, which often leads to sharper bands, as some restriction enzymes bound to DNA are lysed by SDS. 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

Application

Analysis of DNA samples with high amounts of DNA binding proteins. Kinetic experiments. DNA agarose gel analysis after DNA restriction digestions, ligation or dephosphorylation reactions.

Features

Two-color tracking of DNA migration during electrophoresis.

1% SDS eliminates DNA-protein interactions, prevents appearance of additional bands due to annealing of DNA molecules with cohesive ends.

100 mM EDTA inhibits metal-dependent nucleases.
