Thermo Scientific O'RangeRuler DNA Ladders are designed for precise sizing of PCR products and other double-stranded DNA fragments in agarose or non-denaturing polyacrylamide gels.
O'RangeRuler series is characterized by its 'step ladder' design. The chromatography-purified DNA fragments are precisely separated by a consistent increment (e.g., 5 bp, 10 bp, 20 bp, 50 bp, 100 bp, 200 bp, or 500 bp). The design enables accurate and precise sizing of DNA fragments. Not recommended for DNA quantification.
All O'RangeRuler DNA Ladders are supplied with 6X Orange DNA Loading Dye for sample DNA. Orange G dye can be used to monitor DNA migration in agarose or polyacrylamide gels and migrates at 50 bp in a 1% agarose gel.
Highlights
Sustainability features
Ready-to-use O'RangeRuler DNA ladders can be stored at room temperature for up to 24 months. The ladder is shipped at ambient temperature, using optimized right-sized packaging and 100% recyclable packaging reducing waste.
The GelRed or GelGreen nucleic acid dyes can be used with our DNA Ladders. Nucleic acid binding dyes can affect DNA migration during electrophoresis, therefore we highly recommend post-staining of gels. Please follow the gel staining protocol provided by the manufacturer of nucleic acid gel dyes.
For fast sizing and quantification of double-stranded DNA, we recommend using FastRuler DNA Ladders. These ladders are easily resolved in a short separation distance after an 8-14 min run.
Each of Thermo Scientific DNA and RNA ladders has a recommended voltage given in V/cm. Please refer to the gel picture in the product information sheet. V/cm stands for the amount of voltage recommended per cm of the distance between the two electrodes of the gel box (not gel length).
Thermo Scientific DNA and RNA ladders have 5′-phosphate and 3′-hydroxyl groups.
