The DNA Ladders are ladders with defined sizes. The ladders are not intended for use in quantitative analysis. Each ladder is provided with a tube of 6X Blue/Orange Loading Dye.
PCR Markers: 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.
100bp DNA Ladder: Eleven fragments that range in size from 100bp to 1,000bp in 100bp increments with an additional band at 1,500bp. The 500bp fragment is present at increased intensity for easy id...

100bp DNA Ladder: Eleven fragments that range in size from 100bp to 1,000bp in 100bp increments with an additional band at 1,500bp. The 500bp fragment is present at increased intensity for easy identification. The ladder is dephosphorylated and ready for 5´ end-labeling with radioisotopes using T4 Polynucleotide Kinase, allowing visualization by autoradiography.
1kb DNA Ladder: Thirteen blunt-ended fragments with sizes ranging from 250bp to 10,000bp. The 1,000bp and 3,000bp fragments have increased intensity relative to the other bands on ethidium bromide-stained agarose gels for easy identification. All other fragments are of equal intensity. The ladder is dephosphorylated and ready for 5´ end-labeling with radioisotopes using T4 Polynucleotide Kinase, allowing visualization by autoradiography.
Recommended Loading: Load 5μl/lane.
