PCR product analysis 

1. Mix 6uL Tar PCR product AraC and 4uL dye, then load into the well#10 of gel*#2

2.run the gel for about 30 mins, then take a picture.

3.Cut product band to be Zymo purified

 cut out bands minimizing extra gel matter.
 put in ependorf tube and add 600uL of Zymo ADB buffer (brown bottle).
 heat at 55, shake and/or vortex until the gel has dissolved.
 If the DNA is <300bp add 250uL of isopropanol (mine was above 900bp)
 transfer into the Zymo column inside a collection tube (small clear guys)
 spin 15 sec through, discard waste.
 Add 200 uL of Zymo Wash Bbuffer (which is basically 70% ethanol)
 spin  15 sec through, discard waste.
 Add 200 uL of Zymo Wash Buffer
 spin 15 sec through, discard waste.
 spin for 90 seconds, full speed to dry.
 elute with water into a fresh Eppendorf tube ( I used 8ul)

4.Store the rest of PCR product in freezer

5. Store the purified gel product

• Performed by GSI

 spin through 15 seconds, discard waste.
 Add 200 uL of Zymo Wash Buffer
 spin through 15 seconds, discard waste.
 spin for 90 seconds, full speed to dry.
 add water and elute with water (spin 60s) into a fresh Eppendorf tube labeled (I used 50ul)
 

3. Skip running a gel

4. Set up amplification "PCA2 lz_IILK"

              32.5 ul H2O

• PCA2 program run by GSI

   2 min initial denature at 94°C
   30 sec denature at 94°C
   30 sec anneal at 60°C [This should be high, as your outer oligos now have a huge overlap with the correct product]
   30 sec extension at 68°C
   repeat 2-4 30 times total

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

NheI/BamHI Digest

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

For PCA 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 37°C for 1 hour. 3. Proceed to another Zymo small fragment cleanup

          Add 100 uL of Zymo ADB buffer (brown bottle) to the reaction.

Transfer into the Zymo column (small clear guys) Add 500uL of Ethanol and pipette up and down to mix spin through (15s), discard waste. Add 200 uL of Zymo Wash Buffer (which is basically 70% ethanol) spin through (15s), discard waste.

          Add 200 uL of Zymo Wash Buffer

spin through, discard waste. spin for 90 seconds, full speed to dry. elute with water 8uL (spin 60s) into a fresh Eppendorf tube and store on ice

note: I did not use wobble for this digestion, therefore ligation might not work

1. transfer melted gel solution into the Zymo column inside a collection tube (small clear guys) 2. spin through (15 sec), discard waste. 3. Add 200 uL of Zymo Wash Bbuffer (which is basically 70% ethanol) 4. spin through (15 sec), discard waste. 5. Add 200 uL of Zymo Wash Buffer 6. spin through (15 sec), discard waste. 7. spin for 90 seconds, full speed to dry. 8. elute with water 8uL and spin for 60 seconds into a fresh Eppendorf tube and store on ice

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
