Transformation Results

Colony Check

Plate Colonies
M 34 no
M 12 yes
I 34 no
I 34 yes
1-3A 34 yes
1-3A 12 yes

  • 1-3A had colonies in lated on mediums containing 34 ug/uL of chloramphenicol
    • So the medium and antibiotic consentration seems ok,
  • Medium on which M 12 was plated was inoculated with chloramphenicol after solidification so there were some irregularities and colonies on the fringe
  • Colonies of 1-3A and 12 were obviously different

→ So we suspected issues in Ligation and DNA concentration bused for transformation

Estimation of 1-3A Consentration

Electrophoresis of 1uL of 1-3A DNA
  • Added 1 uL of 1-3A into 30 uL of competent cells
  • Transformation was successful
  • Electrophoresed 1 uL of 1-3A,calculated amount of transformed DNA

→Estimated concentration 2 ng/uL

Ethanol precipitation of pSB1C3 and Ligation

Ethanol precipitation

  1. Added 8.2 uL of sodium acetate [3 M]
  2. Added 205 uL of Ethanol [100%] and mixed
  3. Centrifuge at 15,00rpm, 4C for 10 min
  4. Discarded supernatant and added 500 uL of Ethanol [70%], mixed
  5. Centrifuge at 15,00rpm, 4C for 5 min
  6. Discarded supernatant
  7. Dried via vacuum desiccator
  8. Added 8.2 uL of ADW を加え,元の10倍に濃縮する
  • Concentration increased 10 fold

Ligation

  1. Mixed 8.2 uL of DNA solution with the same volume of Ligation Solution
  2. Added extra 1 uL of T4 ligase
  3. Incubated at 16C for 30 min

Tomorrow will do aditional Electrophoresis gel extraction and transformation
