Thermo Scientific O'RangeRuler 5 bp DNA Ladder is designed for precise sizing of PCR products and other double-stranded DNA fragments in agarose or non-denaturing polyacrylamide gels. It is a step ladder with 5 bp differences between the DNA fragments. It consists of purified and ligated blunt-ended basic unit repeats of 5 bp. Not recommended for DNA quantification.

O'RangeRuler 5 bp DNA Ladder is 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. It is the preferable dye when visualization of small DNA fragments is important.


• Step ladder with 5 bp increments
• Sharp bands, easy-to-remember fragment sizes
• Evenly spaced reference bands
• Ready-to-use—premixed with 6X Orange Loading Dye for direct loading and room temperature storage
• Supplied with loading dye for sample DNA
