In the gel and in the tank, the purity and strength of buffers determine not only the electrical parameters of electrophoresis but also the structure and solubility of the biomolecules under study. Buffer quality is as important for electrophoresis results as the gel matrix itself.Produced to the most exacting standards in the industry, National Diagnostics buffers are stable and pure. National Diagnostics buffers eliminate weighing and mixing, save time and help ensure reproducible results.
