Gel Extraction

Materials

You will need:

  • Fermentas GeneJET Gel Extraction Kit
  • Microcentrifuge tubes
  • Microtiter pipette & tips

Extra Notes

  • All steps should be carried out at room temperature.
  • All centrifugations should be carried out in a microcentrifuge at > 12,000xg (10,000-14,000 rpm, depending on the rotor type)

Procedure

  • Cut out gel slice with the desired DNA fragment and weigh gel.
  • Add 1:1 volume of binding buffer to gel slice. (Eg. 100μL of binding buffer for every 100mg of agarose gel.)
  • Incubate gel solution at 50°C-60°C for 10 minutes. Inverting tube helps melting process.
  • Transfer solution to spin column.
  • Centrifuge for 30-60 seconds. Discard flow-through and place spin column back into same collection tube.
  • Add 700μL of wash buffer and centrifuge for 1 minute.
  • Discard flow-through and the centrifuge empty column for 1 minute.
  • Place the column into a fresh 1.5mL microcentrifuge tube.
  • Add 50μL of elution buffer to the column.
  • Centrifuge for 1 minute. Keep the flow-through.

Purpose

To purify the DNA from the gel.
