Today we need to run a dilution series to test the titer of our mutated phage stock. We also need to start selecting for small plaques and learning how to pick them and titer them out. We also should run a UV test on the mutated phage stock compared to the normal stock.

We picked one plaque off of the 180 sec UV plate sample. We suspended it in 1 mL of broth, and then UV-ed 20 uL samples at 45 second intervals. The number of plaques decreased the longer the samples sat under UV light. The samples were irradiated from 0 sec to 4 min 30 sec.

As a control, we diluted the T4Do stock to 10^-6 and tested 20 uL at 45 sec intervals (up to 6 min) under UV light.

Also, we diluted the T4 mutagenized stock to 10^-6 and tested 20 uL at 45 sec intervals (up to 4 min 30 sec) under UV light.

UV tests were done by placing 20 uL spots on parafilm and placed in a BSL-2 hood with the UV light turned on.
