- Manufacturer
A synthetic marker with 17 double-stranded DNA fragments from 50 to 1,500 bp, suited to small fragments and short PCR products. The 200, 500 and 1,200 bp bands are stronger and serve as references, while all other bands have uniform intensity. It is supplied dissolved in buffer with Orange G loading dye, which runs below 50 bp and does not mask the smallest bands.
Key features
Ready to use
Premixed with 6x loading dye: load 5 µL per lane.
Fine resolution
Bands every 50 bp up to 500 bp, then every 100 bp up to 1,000 bp, plus 1,200 and 1,500 bp.
Three reference bands
200, 500 and 1,200 bp are brighter for instant orientation.
Dye that keeps bands visible
Orange G runs below 50 bp, so even the shortest fragments stay visible.
Applications
- Molecular weight standard for DNA electrophoresis
- Sizing DNA fragments from 50 to 1,500 bp
- High-percentage agarose gels, e.g. 2% in TAE
