Our cloning strategy requires 20ng of Casein-DNA in 1uL. This means we need a final concentration of DNA for cloning to be 20ng/uL.

  1. Quick spin lyophilized DNA in a microcentrifuge.
  2. Add 10uL of 1x Low TE Buffer (Tris/EDTA- low refers to the concentration of EDTA. If EDTA is too high in your final cloning reaction, you can inhibit Cation-dependent enzymatic reactions. EDTA is a di-cation chelator and pretty much absorbs all free Ca2+, Mg+ and Mn+ in DNA-based reactions.
  3. Flick the tube - vigorously.
  4. Quick spin tube again (15s)

Use 1uL of the DNA when cloning.
