Thermo Scientific O'GeneRuler 50 bp DNA Ladder, ready-to-use is recommended for sizing and approximate quantification of double-stranded DNA on agarose or polyacrylamide gels. The ladder is a mixture of chromatography-purified individual DNA fragments.
O'GeneRuler 50 bp DNA Ladder, ready-to-use is premixed with 6X Orange DNA Loading Dye for direct loading on gel. 6X Orange DNA Loading Dye contains xylene cyanol FF and orange G. In a 1% agarose gel, orange G dye migrates at 50 bp. Therefore, O'GeneRuler 50 bp DNA Ladder is ideal when visualization of small DNA fragments is important.
The ladder is supplied with 6X Orange DNA Loading Dye for sample DNA.
