The PCR Marker consists of a proprietary plasmid that is digested to completion with appropriate restriction enzymes to yield 5 double-stranded DNA bands suitable for use as molecular weight standards for agarose and acrylamide gel electrophoresis

The digested DNA includes fragments ranging from 50-766 base pairs. The approximate mass of DNA in each of the bands is provided (assuming a 0.3 μg load) for approximating the mass of DNA in comparably intense samples of similar size. Comes supplied with 1 vial of Gel Loading Dye, Purple (6X), no SDS.
