  • λ DNA-Mono Cut Mix


    The Mono Cut Mix is a mixture of intact lambda DNA and lambda DNA separately digested with ApaI, KpnI, XbaI and XhoI. The fragments have been filled in with DNA Polymerase I Large (Klenow) Fragment to prevent re-annealing. These fragments are best separated by Pulsed Field Gel Electrophoresis.The approximate mass of DNA in each of the bands is provided (assuming a 0.5 μg load) for approximating the mass of DNA in comparably intense samples of similar size.

    Comes supplied with 1 vial of Gel Loading Dye, Blue (6X).


    PFGE separation of 0.5 µg of Lambda Mono Cut Mix. 1% agarose gel, 0.5X TBE, 6 V/cm, 15°C for 20 hours. Switch times ramped from 0.5-1.5 seconds.

    1. These fragments are best separated by Pulsed Field Gel Electrophoresis. Alternatively Lambda Mono Cut Mix can be separated by conventional gel electrophoresis using the following conditions: 0.5 μg Lambda Mono Cut Mix, 0.4 % agarose gel, 1X TAE, 20-30 V, 25°C for 24 hours.
    2. 1X Gel Loading Dye, Blue:
      2.5% Ficoll-400
      11 mMEDTA
      3.3 mM Tris-HCL (pH 8.0@25°C)
      0.017% SDS
      0.015% bromophenol blue
