These products are supplied as 50uL aliquots pre-mixed with loading buffer and loading dye that are ready to load straight onto an agarose gel. At the recommended volume of 10uL per well, there is sufficient material for five runs. The high stability of these products means you can store unused material for up to 4 weeks in a refrigerator, or up to 6 months in a freezer.
