W 6.14.06

1. Miniprep of the 3 BioBricks Plasmids (according to standard protocol)

2. Double digest of the 2 R0 (lac promoter) and 2 E0 (gfp) samples

3. Phosphatasing of 2 R0 samples to prevent self-ligation

4. Ran R0 and E0 samples on gel to separate out the gfp from the E0-plasmid

5. Gel extracted R0 plasmid (~2.1 kb, linearized by digestion) and E0 gfp fragment (~0.9kb)

Tu 6.13.06

1. Picked Colonies of Existing BioBrick Transformants

  • Picked:
 3 colonies of E7, 
 2 colonies of E0, 
 2 colonies of R0, and numbered accordingly
  • Grew each colony in 5mL LB + 5uL of 50mg/mL Amp (1:100 dilution).

2. Ran Gel of DNA Nanostructures

  • Ran 2% agarose gel of the nanostructure reaction and the 2 controls for ~40 min at 130V. (NB: Only left four lanes are ours.)

 1kb Ladder | Oligo + Scaffold | -Oligo | -Scaffold

M 6.12.06

1. Folded DNA Nanostructures Using Shawn's Pre-designed Oligo Staples and Scaffold ssDNA

oligos + scaffold

2. Transformed Bacteria with Existing BioBrick Plasmids

  • Transformed each BioBrick plasmid below into OneShot Top10 competent cells (Invitrogen) according to the following protocol.
 R0010 (lac operon promoter),
 E7104 (T4 promoter + gfp), 
 and E0241 (gfp).

Top10 Transformation

 Thaw cells; aliquot out ~30uL per transformation.
 Add desired amount of plasmid DNA (1 uL in this case?) to cells and leave on ice for 30 min.
 Heat shock at 37&degC for 30 sec in a heating block.  
 Ice for 2 min.
 Shake in 37%deg incubator for 1 hr.
 Pour onto plates with the required antibiotic (carbinomycin in this case); spread with beads or plate spreader.
 Incubate plates in 37%deg incubator overnight.
