λ phage DNA from E. coli by Molecular Depot is a methylated lambda phage DNA prepared from Escherichia coli host strain W3110, supplied at 0.3 mg/mL. Lambda DNA is a 48.5 kb linear molecule with well-mapped restriction sites, which is why it is the standard test substrate. It is used as a substrate for restriction enzymes and nucleases, as a size marker after digestion and as carrier DNA. Each unit contains 500 µg. MBP supplies Molecular Depot research reagents to research labs in the United States, Canada and worldwide.
