6 clones of each in 5 mL LB

Digestion Verification

by Coralie

• Biobricks:
  • BBa_K1707012 #1, #2, #3 and #4
  • BBa_K1707013 #1, #2, #3 and #4
  • BBa_K1707019 #1, #2, #3 and #4

• Mix:
  • 1 µL Buffer FastDigest 10x
  • 0,5 µL XbaI
  • 0,5 µL PstI
  • 2 µL Plasmid
  • 6 µL H2O

Incubation 2h, 37°C

Electrophoresis

by Coralie

Agarose gel, 1% Migration 100V

Verification by digestion with XbaI and PstI, from left to right: 1. Empty, 2. DNA Ladder, 3. BBa_K1707012#1, 4. BBa_K1707012#2, 5. BBa_K1707012#3, 6. BBa_K1707012#4, 7. BBa_K1707013#1, 8. BBa_K1707013#2, 9. BBa_K1707013#3, 10. BBa_K1707013#2, 11. Empty, 12. Empty

Verification by digestion with XbaI and PstI, from left to right: 1. Empty, 2. DNA Ladder, 3. BBa_K1707019#1, 4. BBa_K1707019#2, 5. BBa_K1707019#3, 6. BBa_K1707019#4, 7. Empty

We can conclude that all biobricks are OK

Soil experiment

by Coralie and Johan

Soil

Observation of J0 plates: there are a lot of colony in each.

Control (-):

• MCK + Tet: 40 pink colonies
• MCK + Cm: 10 pink colonies
• MCK + Spectino: 1 pink colony
• MCK: 100 pink colonies and a lot of white colonies

We can suppose that we have a contamination between our experiment and control. Or maybe we have a MCK problem because we change it during the experiment.

So, we decide to stop the experiment and do some test:

• Soil + H2O on new MCK
• Soil + LB on new MCK
• LB on new MCK
• MCK alone

Incubation over night, 37°C

New culture

by Pauline

• BBa_K1707005
• BBa_I13602

With plasmid: PIJ773

Incubation at 37°C, 250 rpm

Member present:

• Instructors: Alice
• Students: Coralie, Audrey, Pauline, Johan and Seong-Koo
