ProMega-Markers® Lambda Ladders are prepared by concatemerizing λ phage DNA into multimers ranging in size from 50kb to 800kb and up, with each multimer, or rung, of the 20-step ladder differing in size by one λ genome (approximately 48.5kb). The concatamer-based ladders are embedded in dye-colored, 0.5% agarose string molds in 50mM EDTA. The ladders are intended for use as markers in pulsed-field gel electrophoresis. The ladders are not intended for use in quantitative analysis.

Storage Buffer: 50mM EDTA (pH 8.0) with orange G.
