The Thermo Scientific™ GeneRuler Express DNA Ladder is a ready-to-use molecular weight marker designed for rapid and reliable sizing and quantification of double-stranded DNA fragments from 100 to 1,000 base pairs (bp). Comprising individual chromatography-purified DNA fragments, the ladder ensures sharp, uniform bands and precisely defined quantities in each fragment—making it suitable for routine agarose gel electrophoresis and semi-quantitative analysis.
Supplied pre-mixed with 6X TriTrack DNA Loading Dye, this ladder enables direct loading, simplifies workflow, and facilitates easy tracking of DNA migration using three distinct tracking dyes. With room temperature stability for up to 24 months, it also supports sustainable lab practices and reduces cold chain shipping costs.
Key Features
- Size Range: 100 bp to 1,000 bp
- Fragment Count: 10 individual DNA fragments
- Pre-mixed with 6X TriTrack DNA Loading Dye (Xylene Cyanol FF, Bromophenol Blue, Orange G)
- Ready-to-use format – no additional buffer or preparation needed
- Sharp and quantifiable bands enable accurate sizing and estimation of sample DNA
- Room temperature stable for up to 2 years
- Shipped and stored at ambient temperature to reduce waste and environmental impact
- Compatible with 1–2% agarose gels and common nucleic acid stains (e.g., ethidium bromide, SYBR Safe)
