25bp DNA Step Ladder
The DNA Step Ladders are ladders of defined sizes with exact incremental steps between bands. The ladders are not intended for use in quantitative analysis. Each ladder is provided with a tube of 6X Blue/Orange Loading Dye. The fragments may be stained with ethidium bromide. 25bp DNA Step Ladder: Twelve DNA fragments ranging from 25bp to 300bp in 25bp increments. An 1,800bp backbone fragment is also visible. The 300bp band is ~3 times more intense than all other bands. Recommended loading: 5microl/lane.
