➨ Select week number from the table above...

Week 0

2 June2011 (Tue)

23 June (Thu)

1.      Measure OD of transfer

Ø   All tubes’ OD > 0.55

Ø   Due to contamination in the step of picking colonies. We shouldn’t put the pipette tips into the tubes since our medium does not contain antibodies

2.      Repeated the experiment from picking colonies and inoculation

Ø   Only DH5α is used

Ø   7 hours inoculation

Ø   Inoculation failed.

3.      Restarted from culturing E.coli on agar plate

4.      Restriction cut and Double Digestion

Ø   HR   20ng/ul

Ø   T7   20ng/ul

Ø   Since there are not enough solution(a 50ul system should have at least 200ng of DNA) to make up a 50ul system, we modify the system to 25ul.

4.      Spread plates with antibiotics C, T respectively

5.      Pick colony from T71T3, HR1T3, 3-way ligation plates from refrigerator and then inoculate overnight

6.      We unfortunately make a mistake that because the OD was measured and spinned all of the solution, whereas the start solution should be spinned with accordance with the volume calculated from the measurement of the OD. Therefore, the whole experiment needs to be redone.

All volume to be spinned because the OD of NaCl sets are too small so the total volumes are still inadequate. As a result, a back up set without IPTG by inoculation was prepared and collected on 12-8-2011. It was found that the DH5α plate has been used up for cline picking so later transformation and plate spreading is need. Besides, it was found that there is only little amount of 1000K anti-biotic too.
