Catalog Numbers: P5472, P5722, P5972, and P6097
Store at Room Temperature

Synonym: DNA Agarose Gels

Product Description

These gels are suitable for separating nucleic acids, giving sharp DNA bands and low background fluorescence. DNase activity and DNA binding are not detected. The gels are cast using a 1x TBE (0.089 M Tris-borate, pH ~8.3, containing 2 mM EDTA) buffer system with ethidium bromide (0.5 µg/ml) included in the gel for easy visualization.

Store the gels flat at room temperature. DO NOT FREEZE. Limit exposure to light.


Precast Agarose gels require less than 5 minutes to set up.

  1. Peel the paper backing from the adhesive strips on the bottom of the tray.

  2. Peel off the lid. Leave the gel in the tray.

  3. Press the tray directly onto the chamber platform. Align the wells so the DNA samples will run straight.

  4. Pour 1x TBE electrophoresis buffer in the chamber to a depth of 5 mm OVER the flange of the tray.

  5. Load the DNA sample (≤15 µl volume).

  6. Electrophorese the gels at ≤10 V/cm for 30 minutes. Lower voltages for longer times are acceptable.
    Note: For DNA fragments ≥5 kb, use 1–5 V/cm and increase the run time.

  7. Remove the gel from the tray to photograph/document and/or destain.
