Today I did another round of mutagenesis using the lysis inhibition technique. I did two flasks. The first flask had 20 ug/mL of adenine which was added with the bacteria and 25 mL of LB broth; the second flask had 40 ug/mL of adenine added with the bacteria and 25 mL of LB broth. Both flasks incubated at 37C on the shaker for 3.5 hrs until slightly turbid. I then added 200 ug/mL of bromodeoxyuridine, 20 ug/mL of uracil, and .5 mL of phage to flask one; I added 400 ug/mL of bromodeoxyuridine, 40 ug/mL of uracil, and .5 mL of phage to flask two. They incubated in the same location for 3 hours. | Today I did another round of mutagenesis using the lysis inhibition technique. I did two flasks.

Results from 15 July 2013 - We got our results from the titer test last time on the M9 and LB lysis inhibition test. For the LB plates, we got 9 plaques on the 10^-10 plate, for a total of 9x10^12 pfus/mL. We were extremely excited about these results. The M9 was significantly less (we sort of expected this because we could not induce lysis as well with chloroform) with no plaques on the 10^-9. The spot tests confirmed these results (plaques on 10^-10 for the LB and plaques only down to 10^-6 for M9).
Today I did another round of mutagenesis using the lysis inhibition technique. I did two flasks. The first flask had 20 ug/mL of adenine which was added with the bacteria and 25 mL of LB broth; the second flask had 40 ug/mL of adenine added with the bacteria and 25 mL of LB broth. Both flasks incubated at 37C on the shaker for 3.5 hrs until slightly turbid. I then added 200 ug/mL of bromodeoxyuridine, 20 ug/mL of uracil, and .5 mL of phage to flask one; I added 400 ug/mL of bromodeoxyuridine, 40 ug/mL of uracil, and .5 mL of phage to flask two. They incubated in the same location for 3 hours.
The purification group also centrifuged (in CsCl gradient) the T4 stock and the T4 LB mutagenesis / lysis inhibition sample. Hopefully they will return it to us separated into individual fractions.
