May 2007

May 14

  1. Made the same as May 15, but did not use Type 1 (milliQ) H2O, so the solutions were discarded.

May 15

  1. Made 1M CaCl2, and glycerol/CaCl2 solutions
    1. 1M CaCl2 Solution: 100mL was made
      1. CaCl2 Dihydrate = 146.986 g/mol
      2. 100mL of 1M CaCl2 requires 14.699g CaCl2 Dihydrate
    2. Glycerol/CaCl2 Solution: 30mL was made
      1. 5.00mL of 60% glycerol solution
      2. 3.00mL of 1M CaCl2
      3. 22.00mL of Type 1 (milliQ) H2O

May 16

  1. Transformation of Cells:
    1. Transformed 1 vial of cells with Jun vector, and another vial with Fos vector (1uL of vector each); Sterile
    2. Used 400uL of LB (sterile) for each vial
    3. Incubated for 1 hour in shaker at 37C, then incubate overnight at 37C

May 30

  1. Test PCR Machine


June 2007

June 4

  1. Made Kanamycin plates
    1. 200mL of Agar
    2. 200mL of 2x LB
    3. 2mL of Kanamycin

June 20

Today: extract DNA from plates, transform, plate on amp plates.

I - Extraction of DNA from Plate (5M and 9G)

  1. Puncture foil with pippette tip
  2. Add 15uL of Type 1 water
  3. Remove all liquid (with DNA in solution)

II - Transformation of extracted DNA

  1. Chill cells on ice for 10 min
  2. Heat shock cells at 42°C for 30 sec
  3. Add DNA for cells
  4. Add 500uL of 42°C SOC medium to each vial
  5. Incubate on ice for 1 min
  6. Place in 37°C shaker incubator for 1h 30min
  7. Plate onto 4 separate amp plates
    1. 25uL R0062
    2. 25uL C0060
    3. 400uL R0062
    4. 300uL C0060
  8. Place into 37°C incubator at 3:55PM

Next: seed, miniprep and screen the DNA.

June 21

Checked colonies in the 37°C incubator. Well formed colonies were on each plate, so plates (all 4) were transferred to the small fridge (middle shelf on the right).

June 22

Today: miniprep DNA from July 20th transformation

I - Miniprep of Colonies from R25, R400, C25, C300 (indication the biobrick and the amount in uL that was plated)

  1. Transfer 1.5mL of cells suspended in LB into a microcentrifuge tube.
  2. Centrifuge for 2 min at max speed (14000 rpm)
  3. Remove supernatant with pipette and discard.
  4. Add 250uL of buffer P1 and 250uL of buffer P2
  5. Close and invert tubes 6 times
  6. Add 350 uL of buffer N3 (within 5 min of adding buffer P2)
  7. Close and invert 6 times
  8. Centrifuge for 10 min at 13000 rpm
  9. Carefully pipette off the supernatant into a Qiaprep spin column. NB: for sample R400 a large amount of supernatant was discarded. No reason, stupid move by Tim.
  10. Centrifuge spin column for 60 sec
  11. Discard flow-through
  12. Add 750uL of buffer PE
  13. Centifuge for 60 sec (max speed)
  14. Add 50uL of sterile water (of EB buffer could be used)
  15. Let stand for 1 min then centrifuge for 1 min
  16. Transfer flow-through to a new micro-centrifuge tube (one with a cap) with a pipette.
  17. Stored in -20°C freezer (green box labelled "Team 2")
  18. Remaining cells in LB stored in small fridge

Next: Screen the DNA.

June 26

Today: Screen of R0062 and C0060 from July 20th transformation

I - For R0062 add:
1.5uL of buffer 2
1.5uL of 10X BSA
3uL mini-prepped DNA
1uL of XmnI
1uL of XbaI
7uL of sterile water
Total volume = 15uL

II - For C0060
Same as above but no XbaI and 8uL water

Let both sit in 37°C water bath for 1h 40 min (From 3:30PM to 5:10PM)

III - Gel electrophoresis

  1. Add 12uL of water to each R25, R400, C25, C300
  2. Add 3uL of respective digested DNA
  3. Add 1.66uL of loading dye
  4. Gel contains:
    1. Ladder (5uL)
    2. R25 uncut
    3. R25 cut
    4. R400 uncut
    5. R400 cut
    6. C25 uncut
    7. C25 cut
    8. C300 uncut
    9. C300 cut
  5. The remaining uncut mini-prepped DNA was stored in the pink "Team 1" box.
