The Thermo Scientific™ GeneRuler 50 bp DNA Ladder is a reliable, chromatography-purified double-stranded DNA molecular weight marker ideal for sizing and approximate quantification of DNA fragments from 50 bp to 1,000 bp. It consists of 13 precisely defined DNA fragments and is supplied with a 6X TriTrack DNA Loading Dye, allowing three-color tracking during electrophoresis.
This DNA ladder is designed for use in agarose or polyacrylamide gels and can be visualized with ethidium bromide or SYBR Safe. Its consistent band intensity and reference bands enable accurate fragment sizing and semi-quantitative analysis of sample DNA.
Key Features
- Broad size range: 50 bp to 1,000 bp
