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. 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: 5microl/lane
