Transformation of standard components

  • cultured bacteria did grow overnight
  • 1 mL of each tube reserved to make glycerol stock
  • extracted DNA from remaining 4 mL using the standard protocol:
  1. Resuspended pelleted bacterial cells in 250 µl Buffer P1 (w/ RNAse) (kept at 4 °C) and transfered to a microcentrifuge tube.
  2. Added 250 μl Buffer P2 and gently inverted the tube 4–6 times to mix. Waited 2 min.
  3. Added 350 μl Buffer N3 and inverted the tube immediately but gently 4–6 times. Solution became cloudy.
  4. Centrifuged for 10 min at 14,000 rpm.A compact white pellet formed.
  5. Applied the supernatants from step 4 to the QIAprep spin column by decanting.
  6. Centrifuged for 60 s. Discard the flow-through.
  7. Washed the QIAprep spin column with 0.5 ml Buffer PB and centrifuged for 60 s. Discarded the flow-through.
  8. Washed QIAprep spin column by with 0.75 ml Buffer PE and centrifuged for 60 s.
  9. Placed the QIAprep column in a clean 1.5 ml microcentrifuge tube. Eluted with 30 μl water to the center of each QIAprep spin column, let stand for 2 min, and centrifuged for 60 s.</pre>

DNA nanostructure reaction PCR

  • order of lanes: 1) 1kb ladder, 2) full rxn (oligos + scaffold), 3) just scaffold, 4) just oligos
  • run on 2% agarose gel
  • appears that reaction was successful (upload gel image)

DNA nanostructure reaction PCR

Transformation of standard components

  • goal: insert three plasmids (already containing BioBricks) into /E. coli/ in order to amplify them
