Self-circularization of Linear DNA (with T4 DNA Ligase)

  1. In a microcentrifuge tube prepare a solution of linear DNA (25-50ng) in deionized water or TE buffer (10-35µl).
  2. Add:
  3. Incubate the mixture for 1 hour at 22°C .
  4. Inactivate T4 DNA Ligase by heating reaction mixture at 65°C for 10 minutes.
  5. Resulting reaction mixture can be used directly for transformation.
