  • Started approximately 30 mL of E coli B liquid culture overnight.


8/20/13

  • Selected for 12 small plaques (S1-S12, relatively large phage) and 12 big plaques (B1-B12, relatively small phage) at respective end of spectrum for 8.14 Mutagen Concentration Test - Seventh Protocol. Spectrum ends were chosen because the likelihood of contamination between different layers of CsCl during the extraction process.

- Worked on editing the abstract for submission.


8/31/13

- Further dilution series and spot test was performed to gain a more accurate idea of phage distribution in CsCl gradient. Specific procedures can be found at 8.26 Mutagen Concentration Test - Eighth Protocol.

- Started approximately 10mL of E coli B liquid culture overnight.
