==PCR product of Tar and PCA1 of Lz-AAAA-1==


===PCR product of Tar===
1. Obtain my oligos hhe0120F(32.6nM) and hhe0120R(32.9nM), dilute each oligo into 100uM by adding 326uL and 329uL ddH2O, respectively. <br>
2. Prepare 10uM of each oligo dilution by mixing
        9uL Water
        1uL 100uM oligo
3. label PCR tube "Tar", and add
        24uL ddH2O
        3.3uL 10x Expand Buffer "2"
        3.3uL dNTPs (2mM in each)
        1uL Oligo hhe0120F, 10uM
        1uL Oligo HHE0120R, 10uM
        0.5uL Template DNA "MG1655 Gen."
        0.5uL Expand polymerase "1"  (lastly)
4. Mix well and centrifuge briefly, then store on ice.

***The next steps (PCR amplification) are running by GSI:
     Note:first 10 cycles have shorter extensions than tha latter 20 cycles.
     Since the size of my predicted product is 802bp, which is under 2kb, we should use 2K55


===PCA1 product of Lz-AAAA-1===
1. label tube "Mix" and add 1uL of each oligo o1, o11, o12, then mix it well and centrifuge.<br>
2. label PCR tube "Lz-AAAA-1 PCA1", and add
     38 uL ddH2O
     5 ul 10x expand buffer
     5 ul 2mM dNTPs
     1 ul oligo mixture (100uM total, mixture of oligos from step 1)
     0.75 ul Expand polymerase
3. Mix well and centrifuge briefly, then store on ice.

***The next steps (JCA/PCA1 Program) are running by GSI:
      a) 2 min initial denature at 94°C
      b) 30 sec denature at 94°C
      c) 30 sec anneal at 55°C [This should be the overlap temp of your oligos - vary as needed]
      d) 30 sec extension at 72°C
      e)repeat 2-4 30 times total

==Analytical gel of PCR product(Tar) and PCA2 of Lz-AAAA1==


===Analytical gel of PCR product(Tar)===
1.Obtain my PCR product Tar
2.label tube "tar-gel", mix 6uL Tar PCR product Tar and 4uL dye, then load into the well(#8) of gel1 prepared by GSI. <br>
3.run the gel for about 30 mins, then take a picture.
4.Save the PCR product of Tar in the freezer for later.



===PCA2 of Lz-AAAA-1===
1. Obtain PCA1 product.
2. Since the product of PCA1 is expected small fragment (less than 300bp0, use small-frag Zymo cleanup procedure:
      a) Add 100 uL of Zymo ADB buffer (brown bottle) to the PCA1 tube.
      b)Transfer all liquid from PCA1 tube into the Zymo column 
      c)Add 500uL of Ethanol and pipette up and down to mix
      d)spin through 15 seconds, discard waste.
      e)Add 200 uL of Zymo Wash Buffer (white bottle which is basically 70% ethanol)
      f)spin through 15 seconds, discard waste.
      g)Add 200 uL of Zymo Wash Buffer
      h)spin through 15 seconds, discard waste.
      i)spin for 90 seconds, full speed to dry.
      j)add 50 uL water and elute with water (spin 60s) into a fresh Eppendorf tube labeled " purified PCA1" [Note: the amount of water added depends on the starting amount of PCA product) 
  Now, the cleaned up assembly reaction as template for PCA2 is collected product into a fresh Eppendorf tube.
3. (Skip running on a gel due to smeary mess) Conduct amplification after zymo cleanup:
      a)label a PCR tube "PCA2 Lz-AAAA-1", then add:
               32.5 ul H2O
               5 ul 2mM dNTPs
               10 ul 5x phusion buffer
               1 ul purified PCA1 product (from step 2)
               1 ul  outer oligo o1 (10 uM)
               1 ul  outer oligo o12 (10 uM)
               0.5 ul phusion
       b) Mix well and centrifuge briefly, then store on ice.
       c) save the purified PCA1 tube in the freezer in case this step fails!

***The next steps (programming) are running by GSI:
             a) 2 min initial denature at 94°C
             b) 30 sec denature at 94°C
             c) 30 sec anneal at 60°C [This should be high, as your outer oligos now have a huge overlap with the correct product]
             d) 30 sec extension at 68°C
             e) repeat 2-4 30 times total

==Zymo Cleanup of Tar PCR product and Lz-AAAA-1 PCA2 product==

===Zymo Cleanup of Tar PCR product===
Since the expected size of PCR Tar product is 802bp, choose regular Zymo Cleanup Procedure to removes the polymerase, dNTPs, buffer, and most of the oligonucleotides from a PCR reaction. It also will remove the buffer and restriction enzymes from a restriction digest reaction:
   1.Add 180 uL of Zymo ADB buffer (brown bottle) to a ~30uL Tar PCR product.
   2.Transfer into the Zymo column (small clear guys)
   3.spin through (15sec), discard waste.
   4.Add 200 uL of Zymo Wash Buffer (which is basically 70% ethanol)
   5.spin through(15sec), discard waste.
   6.Add 200 uL of Zymo Wash Buffer
   7.spin through(15sec), discard waste.
   8.spin for 90 seconds, full speed to dry.
   9.elute with water(30uL) into a fresh Eppendorf tube, (the same volume of water as the volume of the original reaction) store in ice.



===Analytical gel of PCA2 product OF Lz-AAAA-1===
1.Obtain my PCA2 product of Lz-AAAA-1
2.label tube "PCA2-AAAA-1", mix 6uL PCA2-Lz-AAAA-1 product and 4uL dye, then load into the well(#1) of gel2 prepared by GSI. <br>
3.run the gel for about 40 mins, then take a picture.


===Zymo Cleanup of Lz-AAAA-1 PCA2===
Since the size of PCA2 is 139bp<300bp, choose the  small-Frag Zymo Cleanup to removes the polymerase, dNTPs, buffer, and most of the oligonucleotides from a PCR reaction for fragments smaller than 300bp. It also will remove the buffer and restriction enzymes from a restriction digest reaction
   1.Add 100 uL of Zymo ADB buffer (brown bottle) to the PCA2 tube.
   2.Transfer into the Zymo column (small clear guys)
   3.Add 500uL of Ethanol and pipette up and down to mix
   4.spin through (15s), discard waste.
   5.Add 200 uL of Zymo Wash Buffer (which is basically 70% ethanol)
   6.spin through (15s), discard waste.
   7.Add 200 uL of Zymo Wash Buffer
   8.spin through, discard waste.
   9.spin for 90 seconds, full speed to dry.
   10.elute with water 50 uL (Since we add 50 uL at the beginning) spin for 60s into a fresh Eppendorf tube, and store on ice.

 12. incubate at 37 degrees UPSIDE DOWN overnight (GSI will freeze it after 24 hours)


Huiting He 12:56, 28 February 2012 (EST)

since the culture of all of 4 tubes of Lz-AAAA1 and 3 tubes of Tar are clear after colonies incubate overnight (the colonies were picked up by GSI), I need to redo the ligation and transformation and do the miniprep for the successful tar culture. 

==Ligation of NheI/BamHI digests and transformation of Tar and Lz-AAAA-1 individually==
The procedure are same for  these two products(Tar and Lz-AAAA-1)

       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).

[User:Huiting He|Huiting He]] 12:56, 1 March 2012 (EST)

I got one tube of Tar culture and 2 tubes of lz-AAAA1 culture. The liquid of all of them are not clear so I can run the Miniprep purification of DNA.

==Miniprep purification of DNA for one Tar_2 and two Lz-AAAA1_1 and Lz-AAAA1_2 at the same time==
   1. Pellet 2 mL saturated culture Tar by spinning full speed, 30 seconds in a 2mL Microcentrifuge tube.

==Analytical digest(Mapping) for Lz-AAAA1_1 and Lz-AAAA1_2
For my Lz-AAAA1, I chose to use EcoRI/BamHI to digest my product because the product are expected to produce 2 bands (2472+1145bp), that is comparable to the digestion product of original plasmid PBca9525-Bca1834 (2478+1863bp)
   1. Set up the following 10uL reaction in a PCR tube and mix well:
                  6uL ddH2O                  
                  2uL Miniprepped plasmid of Lz-AAAA1(1) or Lz-AAAA1(2)
                  1uL 10x NEB Buffer 2
                  .5uL EcoRI
                  .5uL BamHI 
   2. Incubate at 37°C on the thermocycler for 30 minutes
   3. Run an analytical gel
   4. Take a picture of the gel
[according to the gel, it seems the bands didn't separate well and there are too much DNA load in the gel. I cant make any conclusion based on the gel. I should dilute the DNA Miniprep plasmid and running gel next time.]

Huiting He 15:44, 2 March 2012 (EST)

since I have all 4 miniprep plasmid (2 tar and 2 Lz-AAAA1), I run the Analytical digest (Mapping) for them at the same time.

==Analytical digest (Mapping) for Lz-AAAA1==
According to the gel yesterday, I should dilute my DNA concentration into 0.1X, thus, I mix 9 uL H2O and 1 uL of Lz-AAAA1_1 or Lz-AAAA1_2 to obtain 0.1X concentration.

For my Lz-AAAA1, I chose to use EcoRI/BamHI to digest my product because the product are expected to produce 2 bands (2472+1145bp), that is comparable to the digestion product of original plasmid PBca9525-Bca1834 (2478+1863bp)
   1. Set up the following 10uL reaction in a PCR tube and mix well:
                  6uL ddH2O                  
                  2uL 0.1X Miniprepped plasmid of Lz-AAAA1_1 or Lz-AAAA1_2
                  1uL 10x NEB Buffer 2
                  .5uL EcoRI
                  .5uL BamHI 
   2. Incubate at 37°C on the thermocycler for 30 minutes
   3. Run an analytical gel
   4. Take a picture of the gel


==Analytical digest (Mapping) for Tar==
For Tar, I chose to use only Xbal to digest my product because there are two Xbal restriction enzymes in my product while only one in plasmid PBca9525-Bca1834. Thus, the product are expected to produce 2 bands (3598+682bp, two bands), that is comparable to the digestion product of original plasmid PBca9525-Bca1834 (4335bp, one band)
   1. Set up the following 10uL reaction in a PCR tube and mix well:
                  6uL ddH2O                  
                  2uL Miniprepped plasmid of Lz-AAAA1_1 or Lz-AAAA1_2
                  1uL 10x NEB Buffer 2
                  1 uL Xbal 
   2. Incubate at 37°C on the thermocycler for 30 minutes
   3. Run an analytical gel
   4. Take a picture of the gel

Result: according to gel pic, the Tar-1 only has one band which is not the one we interested. But Tar-2 did has two band that seems like at 3500 and 682 bp. So I can send out the Tar-2 for sequencing.
The bands for lz-AAAA-1 are totally off. So redo the Lz-AAAA-1 part.

      i)spin for 90 seconds, full speed to dry.
      j)add 50 uL water and elute with water (spin 60s) into a fresh Eppendorf tube labeled " purified PCA1" [Note: the amount of water added depends on the starting amount of PCA product) 
  Now, the cleaned up assembly reaction as template for PCA2 is collected product into a fresh Eppendorf tube.
3. (Skip running on a gel due to smeary mess) Conduct amplification after zymo cleanup:
      a)label a PCR tube "PCA2 Lz-AAAA-1", then add:
               32.5 ul H2O
               5 ul 2mM dNTPs
               10 ul 5x phusion buffer
               1 ul purified PCA1 product (from step 2)
               1 ul  outer oligo o1 (10 uM)
               1 ul  outer oligo o12 (10 uM)
               0.5 ul phusion
       b) Mix well and centrifuge briefly, then store on ice.
       c) save the purified PCA1 tube in the freezer in case this step fails!

***The next steps (programming) are running by GSI:
             a) 2 min initial denature at 94°C
             b) 30 sec denature at 94°C
             c) 30 sec anneal at 60°C [This should be high, as your outer oligos now have a huge overlap with the correct product]
             d) 30 sec extension at 68°C
             e) repeat 2-4 30 times total

===Zymo Cleanup of Lz-AAAA1 PCA2===
Since the size of PCA2 is 139bp<300bp, choose the  small-Frag Zymo Cleanup to removes the polymerase, dNTPs, buffer, and most of the oligonucleotides from a PCR reaction for fragments smaller than 300bp. It also will remove the buffer and restriction enzymes from a restriction digest reaction
   1.Add 100 uL of Zymo ADB buffer (brown bottle) to the PCA2 tube.
   2.Transfer into the Zymo column (small clear guys)
   3.Add 500uL of Ethanol and pipette up and down to mix
   4.spin through (15s), discard waste.
   5.Add 200 uL of Zymo Wash Buffer (which is basically 70% ethanol)
   6.spin through (15s), discard waste.
   7.Add 200 uL of Zymo Wash Buffer
   8.spin through, discard waste.
   9.spin for 90 seconds, full speed to dry.
   10.elute with water 50 uL (Since we add 50 uL at the beginning of digestion) spin for 60s into a fresh Eppendorf tube, and store on ice.

===Analytical gel of Zymo-clean PCA2 product of Lz-AAAA1===
1. mix 6uL PCA2-Lz-AAAA1 product and 4uL dye, then load into the well(#6) of gel2 prepared by GSI. <br>
3.run the gel for about 40 mins, then take a picture.

===NheI/BamHI Digest of Wobble Products Lz-AAAA1===
Since the size of Lz-AAAA-1 is small fragment, use the wobble digest
1. set up the following reaction in a PCR tube:
      44 uL eluted Lz-AAAA
      5.7uL NEB Buffer 2
      0.5uL NheI
      0.5uL BamHI
2. Mix thoroughly by slamming the tube upside down on the table, and then a quick spin to move the liquid to the bottom of the tube.
3. Incubate the reaction at 37 degrees on the thermocycler for 1 hour
4. Proceed to another Zymo small fragment cleanup
        a)     Add 100 uL of Zymo ADB buffer (brown bottle) to the reaction.
	b)	Transfer into the Zymo column (small clear guys)
	c)	Add 500uL of Ethanol and pipette up and down to mix
	d)	spin through (15s), discard waste.
	e)	Add 200 uL of Zymo Wash Buffer (which is basically 70% ethanol)
	f)	spin through (15s), discard waste.
	g)	Add 200 uL of Zymo Wash Buffer
	h)	spin through, discard waste.
	i)	spin for 90 seconds, full speed to dry.
	j)	elute with water 44uL (spin 60s) into a fresh Eppendorf tube and store on ice [lz-AAAA1-digpdt]

Competent cells are stored as 200uL aliquots in the -80 freezer as a communal stock.
  1. Thaw a 200 uL aliquot of cells on ice
  2. Add 50 uL of water to the cells (if greater volume is desired)
  3. Add 30 uL of KCM to the cells 
  4. Put your ligation mixture on ice, let cool a minute or two (for Miniprep product, dilute by 10, then use 1uL of dilution)
  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 1 hour
 10. Plate 70+ uL on selective antibiotics, let incubate at 37 degrees overnight

===Picking of colonies=== DONE BY GSI
	▪	For each construct you will pick and later miniprep 2 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

Since all 4 tubes of Lz-AAAA-1 is clear(no grow). Also, the big colonies on the plate is light pink-->they are not the one we want. There still have some small colonies that are white. Since there is not enough time to redo the whole process, I pick another 6 colonies for culturing to check if cell will grow.


Huiting He 13:00, 20 March 2012 (EDT)

All 6 tubes are clear, too. The trial of LZ-AAAA-1 failed.
