O'RangeRuler Ladders
O'RangeRuler™ DNA Ladders are step ladders that consist of basic unit repeats of 10, 15, 20, 50, 100, 200, or 500 bp. The ladders have a higher density of bands at a specific DNA size range and therefore are suitable for more accurate sizing of DNA in agarose or non-denaturing polyacrylamide gels.
Features:
- Step ladders—ligation products of DNA fragments of equal increments
- Sharp bands, evenly spaced reference bands
- Ready-to-use—premixed with loading dye for direct loading
- Room temperature storage
- Supplied with loading dye for sample DNA
