NheI/BamHI Digest for PCR product part SBB1202 and PCA2 product part SBB1230


For PCR product

1. Digest PCR product by adding:

        8uL  of eluted PCR product
        1uL of NEB buffer 2
        0.5 uL of NheI
        0.5 uL of BamHI

2. incubate in thermocycler 37°C for 1 hour. 3. Run an agarose gel and cut out the band to minimize extra gel matter 4. Put in ependorf tube and add 600uL of Zymo ADB buffer (brown bottle) 5. heat at 55°C, shake and/or vortex until the gel has dissolved.

Note: I stopped here because time run out, the melted gel was kept frozen until next lab day

Performed a Ligation and transformation for both parts on Vector PBca9525-Bca1834*


Ligation of NheI/BamHI digests

1.Set up the following reaction

         6.5uL ddH2O
         1uL T4 DNA Ligase Buffer 
         1uL Vector digest *
         1uL Insert digest 
         0.5uL T4 DNA Ligase

2.Pound upside down on the bench to mix 3.Give it a quick spin to send it back to the bottom of the tube 4.Incubate on the benchtop for 30min 5.Put on ice and proceed to the transformation

Transformation by heat-shock

 1. Thaw a 200 uL aliquot of cells on ice
 2. Add 50 uL of water to the cells
 3. Add 30 uL of KCM to the cells 
 4. Put my ligation mixtures on ice, let cool a minute or two 
 5. Add 70 uL of the cell cocktail to the ligation,   stir to mix
 6. Let sit on ice for 10 min
 7. Heat shock for 90 seconds at 42 (longer incubation may work better)
 8. Put back on ice for 1 min
 9. Add 100uL of 2YT, let shake in the 37 degree incubator for 45 minutes
11. plate 75 uL on selective antibiotics 
12. incubate at 37 degrees UPSIDE DOWN overnight**

note: did not add water, also I did a negative control by adding water instead of the ligation.

(*) digestion of vector PBca9525-Bca1834 with NheI/BamHI was done by GSI (**) GSI will freeze

Miniprep purification of DNA

  1. Pellet 2 mL saturated culture Tar by spinning full speed, 30 seconds in a 2mL Microcentrifuge tube.
  2. Dump supernatant
  3. Add 250uL of P1 buffer into each tube. Resuspend the cells thoroughly
  4. Add 250uL of P2 buffer (a base that denatures everything and causes cells to lyse). Gently mix up and down. Solution   
      should become clearer.
  5. Add 350uL of N3 buffer (an acid of pH ~5 that causes cell junk - including protein and chromosomal DNA - to  
      precipitate, and leaves plasmids and other small molecules in solution). Slowly invert a few times, then shake.
  6. Spin in centrifuge at top speed for 5 minutes.
  7. Label blue columns with an alcohol-resistant lab pen.
  9. Pour liquid into columns, and place the columns into the centrifuge. Spin at full speed for 15 seconds.
  10. Dump liquid out of the collectors under the columns (the DNA should be stuck to the white resin)
  11. Wash each column with 500 uL of PB buffer.
  12. Spin in centrifuge at full speed for 15 seconds, then flick out the liquid again.
  13. Wash with 750uL of PE buffer (washes the salts off the resins).
  14. Spin in centrifuge at full speed for 15 seconds and flick out liquid again.
  15. Spin in centrifuge at full speed for 90 sec to dry off all water and ethanol.
  16. Label new Microcentrifuge tubes and put columns in them.
  17. Elute them by adding 50uL of water down the middle of the column (don't let it stick to the sides).
  18. Spin in centrifuge at top speed for 30 seconds.
  19.Take out columns and cap the tubes and store on the ice for mapping.

Pick up colonies and inoculate LB liquid medium for:

Picking of colonies

  Add 4mL of LB media with the appropriate antibiotics to a clean test tube
  Pick a well-isolated, round, and "normal" looking colony with a toothpick
  Drop it in the test tube
  Incubate at 37 overnight
