CircLigase II Reagent Testing[edit]

  • Test new CircLigase II kit that arrived this month

Reaction Mix[edit]

  • 5ul ssDNA control (10pmol total)
  • 2ul 10X Reaction Buffer
  • 1ul 50mM MnCl2
  • 4ul 5M Betaine
  • 1ul CircLiase II Enzyme
  • 7ul H2O
  • Total: 20ul
  • Sample1: New enzyme + kit reagents
  • Sample2: New enzyme + Hosuk's buffer 8-1-2014 + Homemade MnCl2 & Betaine
  • Sample3: Old enzyme (red cap) + kit reagents
  • Sample4: No Enzyme

Procedure[edit]

  1. Incubated at 60C for 1hr
  2. Incubated at 80C for 10min (inactivate)
  3. Take 4ul of each and run TBU gel
  4. ssDNA Zymo column purification
    • Elute 10ul
  5. Exonuclease I Digest half of sample
    • 5ul + 1ul 10X ExoIII Buffer + 4ul H2O
    • 5ul + 1ul 10X ExoIII Buffer + 1ul Exonuclease I + 3ul H2O
  6. Incubate 37C for 45min
  7. Incubate 80C for 15min (inactivate)
  8. Run TBU gel

Conclusion[edit]

  • Both old and new enzyme work
  • Our homemade components work just as well
  • Circularized ssDNA actually runs slightly faster in our TBU gels
