Prep 6 uL product w/ 4 uL loading buffer Placed on wells 9, 10 labeled ROTP and ROCT
Picture taken of gel->does not look correct
Lane 9 has W shaped smear
I do not believe my recordings. Either I switched what lanes I believed was which or one of my products failed. I will switch assumptions and assum 9 ROCT and 10 ROTP
Cut out band which correspond to correct size.
Cut out extra band. 1K band maybe from lane 9 is ROCT
Possible that 1K hidden in smear is actual TP product
No 500 band appeared in lane 10 so its doubtful.

SOE PCR Round 3
PCR 1231ROCT + 1231ROTP with ca998/g00101
Result labeled 1231PCR3
Placed in PCR rack for 1K-2K
sbb1214
Taking digested product from tuesday->zymo column [6]
Too much liquid for 1 column. Performing 2 rounds.
Added 50 uL H2O. This amount was not correct should have only eluded w/8uL. Possible that product is too diluted for later steps to work.
Ligate products
Incubate on benchtop for 30 min 11:12-11:42
Waiting until Friday for transformation
If there is an issue, it will likely be due to 6x dilution of vector
Can restart at 1214Cloning

Looking back on my notes, I did not run the second round of PCA w/ o16 and o12 on pca1.
Restarting
PCA1 with o12, o16, o17
Note from 3/15
My results from the analytical gel would seem to indicate that I had performed the correct reactions even though I did not record them in my notebook. I continue with the restart anyways.

4 Colonies were picked by Zach.
Turns out none of the cell cultures were viable and the plates I created were totally unusable. There are 2 large red clusters where cells survived. The colonies that were picked were likely contamination from when I leaked. It is also possible that the transformation totally failed.
Experiment stopped. sbb1231 inconclusive.

4 colonies picked. All 4 cultures are viable.
Performing miniprep on all 4. [8]

sbb1231
Not enough time to complete the experiment. I can redo the transformation and plating to at least figure out if my products were viable. If white colonies appear the Friday on a plate, I can say that the transformation at least happened.
