Week 7: 06/30/08 - 06/5/08

06/30/08

  • We received sequencing results for BBa_B0030-BBa_C0061 (4th colony and 7th colony): sequences were correct! We decided to keep the 4th colony.
  • Colony PCR for BBa_J23100-BBa_E0240 and BBa_B0030-BBa_C0061: 5 colonies for every plate. Gel showed many working colonies: we chose first colonies for the two ligations.
