All data on this page was collected by the MIT's Biological Engineering undergraduate students in the Fall 2007 as part of a laboratory class, 20.109. It represents the culmination of an ambitious phage redesign project that began at the start of the term. Redesigned phage were tested for phage titers on a "complete" E. coli genome (MG1655), and on the indicated MDS, described in [1]

Green Team

  • Description of MDS strain: MDS60
  • Any notes about titers presented here: did not do a no phage control, M13K07 not grown at same time as other, some TA unevenly spread so uncertain if plaques could be seen.
