Perfect DNA™ Markers Easy-to-remember sizes for routine use in plasmid cloning The Perfect DNA™ Markers contain sets of DNA species having convenient, easy-to-remember sizes for agarose gel analysis. The markers have uniform band intensities except for the indicated reference bands, which are useful for instant band identification. An extra vial of 6X DNA Gel Loading Buffer is included. Perfect DNA™ Markers, 0.05–10 kbp 100 lanes 70540-3 Perfect DNA Markers, 0.1–12 kbp 100 lanes 70087-3 Perfect DNA Markers, 0.5–12 kbp 100 lanes 69002-3 Components: • 1 ml Perfect DNA Markers in 1X DNA Gel Loading Buffer, for markers, 0.05–10 kbp • 500 ml Perfect DNA Markers in 1X DNA Gel Loading Buffer, for markers 0.1–12 and 0.5–12 kbp • 1 ml 6X DNA Gel Loading Buffer

Perfect DNA™ Ladders Evenly spaced DNA markers in ready-to-load format The Perfect DNA™ Ladders contain sets of DNA species having convenient, easy-to-remember sizes for agarose gel analysis. The markers have uniform band intensities and cover a wide range of DNA sizes. They are supplied in a convenient ready-to-load format containing dye and are ideal for routine use. An extra vial of 6X Loading Buffer (for Cat. Nos. 70538-3 and 70539-3) or 6X DNA Gel Loading Buffer (for Cat. No. 70537-3) is included. Perfect DNA™ 50-bp Ladder 100 lanes 70538-3 Perfect DNA 100-bp Ladder 100 lanes 70539-3 Perfect DNA 1-kbp Ladder 100 lanes 70537-3 Components: • 1 ml in 1X Gel Loading Buffer (for Cat. No. 70538-3) or 500 ml in 1X Loading Buffer (for Cat. Nos. 70539-3 and 70537-3)

PCR Markers For accurate sizing of PCR products The PCR Markers contain a mixture of eight defined DNA fragments ranging from 50 to 2000 bp at convenient size intervals for characterizing small DNA products. The markers are supplied in gel loading buffer containing two tracking dyes that do not interfere with UV illumination of ethidium bromide-stained bands. A separate vial of 6X Loading Buffer is included. Each vial of markers is enough for 50 lanes on TBE or TAE agarose stained with ethidium bromide. The recommended amount for loading (5 ml) produces bands of even intensity that are bright, sharp, and easy to photograph. PCR Markers, 50–2000 bp 50 lanes 69278-3 Components: • 25 ml PCR Markers in 1X Loading Buffer • 1 ml 6X Loading Buffer
