50bp 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. 50bp DNA Step Ladder: Sixteen DNA fragments ranging from 50bp to 800bp in 50bp increments plus an 1,800bp backbone fragment. All bands except the 800bp band are of equal intensity; the 800bp band is ~3 times more intense. Recommended loading: 5microl/lane.
