DNA Ladders have defined sizes, and are not intended for use in quantitative analysis.
PCR Markers have six bands of equal intensity of 50, 150, 300, 500, 750 and 1,000bp. The PCR Markers may be run on polyacrylamide gels with less loading volume; however, additional bands may be visible compared to those visible on agarose gels.
Storage Buffer: 10mM Tris-HCl (pH 8.0), 1mM EDTA.
