Procedure

  • Mix reactants thoroughly.
  • Place at 37 C for 3 hours.
  • Increase to 80 C for 20 minutes to kill enzymes (some enzymes need only a 65 C heatkill, check enzyme).
  • Run on a gel and extract product.

Gel Extraction/Purification Procedure

Materials

  • GeneJET Gel Extraction Kit
  • Binding Buffer (1 uL for every mg of agarose gel)
  • 700 uL of Wash Buffer
  • 50 uL of Elution Buffer

Procedure

  • Add the binding buffer to the gel slice in a microcentrifuge tube.
  • Incubate the gel mixture at 50-60 °C for 10 minutes (until melted).
  • Transfer the solution to a GeneJET purification column.
  • Centrifuge for 30-60 seconds at 12000 x g and discard the flow through.
  • Add Wash Buffer and centrifuge for 1 minute.
  • Discard flow through, then centrifuge empty column for 1 minute.
  • Transfer the column into a fresh 1.5 ml microfuge tube.
  • Add Elution Buffer.
  • Centrifuge for 1 minute and collect the flow-through.
