Thermo Fisher, 10488058, TrackIt™ 100 bp DNA Ladder

TrackIt™ 100 bp DNA Ladder is used for sizing and approximate quantification of double-stranded DNA fragments from 100 bp to 2,000 bp during agarose gel electrophoresis. The ready-to-load ladder contains 13 chromatography-purified linear double-stranded DNA fragments and includes prominent reference bands at 2,000, 1,500 and 600 bp for rapid orientation. It is optimized for separation on 1–2% agarose gels and can be visualized after staining with ethidium bromide or SYBR™ Safe stain. Each band contains a defined amount of DNA, allowing approximate comparison with sample DNA quantities. The ladder is premixed with 6X TrackIt™ Cyan/Orange Loading Buffer, whose tracking dyes make electrophoresis progress visible without obscuring most DNA bands. The package contains 500 µL of ladder at 0.1 µg/µL plus 1 mL of loading buffer, providing 50 µg total DNA.
