  • Product Information
    MidRange Marker II is concatemers of λ DNA isolated from the bacteriophage λ (cI857 ind1 Sam7) mixed with XbaI digested λ DNA embedded in 1% LMP agarose and supplied in a GelSyringe™ dispenser. XbaI produces fragments of 24.0 and 24.5 kb. These fragments anneal to and form concatamers with intact λ DNA. It is designed for use as a size marker for pulsed field gel electrophoresis (PFG). Size range: 24-300 kb.

    • Notes
      1. Recommended plug sizes are from 5-10 µl. A 10 µl plug (one small graduation on the GelSyringe volume scale) contains approximately 0.5 µg of DNA. Each GelSyringe yields 50+ plugs.
      2. Melting plugs will cause denaturation of concatemers.
      3. Extrude agarose from GelSyringe carefully and slice plugs from the end with a sharp blade. One plug is sufficient for one lane of a gel. Place the plug at the front of the well and seal with molten agarose. Allow no bubbles to form.
      4. Place plug at the front of the well and seal with molten agarose just above gelling temperature(~42–45°C). Allow no bubbles to form. Never attach the agarose plugs to the gel comb before the gel is poured. Heat from the solidifying gel will cause the Lambda concatemers to denature.
      5. The photograph represents the pulsed field gel separation of Mid Range II Markers using a CHEF apparatus. The 1% agarose gel was run at 6 volts/cm using ramped pulse times from 1 to 25 seconds for 24 hours at 15°C in 0.5X TBE (50 mM Tris-HCl, 50 mM boric acid, 1 mM EDTA) made with Milli-Q™ water.
