DNA Ladders—Thermo Scientific
We offer a broad selection of Thermo Scientific DNA ladders with fragment sizes ranging from 10 bp to 48.5 kb, for accurate analysis of linear double-stranded DNA in agarose or polyacrylamide gels. DNA ladders are manufactured and quality controlled to supersede industry standards. DNA ladders are made of chromatography-purified individual DNA fragments using a proprietary technology for preparation of pharmaceutical-grade plasmid DNA. DNA ladders are stable during prolonged incubation at room temperature and multiple freeze-thaw cycles.
