• Have gtcc instead of atg in prefix location
• Need to put part on Clotho
• Otherwise correct
• Internal oligos are longer than necessary, but would work
• Due to similarity to other part, some oligos are being replaced:

Part Assembly (Wet Lab)

2/17/2010

sbb02

Note: I'll be sharing oligos with Ben for this part.

• Oligo samples were diluted to 100uM in the tubes they came in, then diluted again to 10uM in separate tubes to be used in the experiment.
• Three PCR reactions were prepared (water added first, protein last) in separate tubes (as described in Cloning by PCR) with these oligos/templates:

1. MNF11-F/CA1472 on Bca1455 1-3 (Tube labeled A)
2. ca1461/BDBn15001R on Bca1455 1-1 (B)
3. BDBn15002F/BDBn15002R on Bca1455 1-2 (C)

24uL ddH2O
3.3uL 10x Expand Buffer "2"
3.3uL dNTPs (2mM in each)
1uL Oligo 1, 10uM
1uL Oligo 2, 10uM
0.5uL Expand polymerase "1"
0.5uL Template DNA

• The predicted products for all three are below 2000kb, so the reaction mixtures should be PCRed up using the 2k55 temperature program.
• The GSIs get to do the actual PCRing.. (aka putting the tubes in the thermocycler and choosing the program, pressing the button, and waiting.)

sbb06

• Completed initial assembly step (as described in PCA Gene Synthesis) in the construction of sbb06 by PCA.

OK, so you've got a bunch of oligos, now what? First, use this recipe and program to do initial assembly of the oligos (do a separate one of these reactions for each chunk you're assembling):
Recipe

   1. 38 uL ddH2O
   2. 5 ul 10x expand buffer
   3. 5 ul 2mM dNTPs
   4. 1 ul oligo mixture (100uM total, mixture of oligos after combination of 100uM stocks)
   5. 0.75 ul Expand polymerase 

Program (can run JCA/PCA1)

   1. 2 min initial denature at 94oC
   2. 30 sec denature at 94oC
   3. 30 sec anneal at 55oC [This should be the overlap temp of your oligos - vary as needed]
   4. 30 sec extension at 72oC
   5. repeat 2-4 30 times total 

• Again, the GSIs ran the program.

2/22/2010

sbb02

• PCR tubes were retrieved (A, B, and C) after the reactions were completed by the GSIs.
• All three samples were prepared for a preparative gel.
  • 6uL PCR product + 4uL loading buffer
• The gel with my samples was run by JHL.

• My PCR products (lanes 10, 11 ,12) appear to be the correct sizes.
• I mistakenly left lab early, and when I came back at 4:30pm, Will and Chris told me that they had already cut the bands out for me and melted them in 650uL ADB buffer (as specified in SOEing PCR).

sbb06

• Small-frag Zymo Cleanup was performed to purify PCA Assembly.

The following procedure 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 reaction.
   2. Transfer into the Zymo column (small clear guys)
   3. Add 500uL of Ethanol and pipette up and down to mix
   4. spin through, discard waste.
   5. Add 200 uL of PE or Zymo Wash buffer (which is basically 70% ethanol)
   6. spin through, discard waste.
   7. Add 200 uL of PE or Zymo Wash buffer
   8. spin through, discard waste.
   9. spin for 90 seconds, full speed to dry.
  10. elute with water into a fresh Eppendorf tube

• The reaction mixture for amplification of the assembled fragments was prepared.

Now, you need to do an amplification of the correct full-length chunks. Clean up the assembly reaction with a zymo column; don't bother running it on a gel - it'll be a smeary mess and won't really help you. Save the purified product in case this step fails! For the amplification reaction, do a normal phusion program with 1 ul of the cleaned up assembly reaction as template, and using the outermost oligos for the chunk. That is:
Recipe

   1. 1 ul each outer oligo (10 uM)
   2. .5 ul phusion
   3. 10 ul 5x phusion buffer
   4. 5 ul 2mM dNTPs
   5. 32.5 ul H2O 

Program

   1. 2 min initial denature at 94oC
   2. 30 sec denature at 94oC
   3. 30 sec anneal at 60oC [This should be high, as your outer oligos now have a huge overlap with the correct product]
   4. 30 sec extension at 68oC
   5. repeat 2-4 30 times total 

• The program was done by the GSIs.

2/24/2010

sbb02

• PCR product mixture (A+B+C) was purified by Zymo Gel Purification and eluted in 50uL ddH2O:

All spins until the drying step are 15 second full speed spins. 

   1. cut out bands minimizing extra gel matter.
   2. put in ependorf tube and add 600uL of Zymo ADB buffer (brown bottle).
   3. heat at 55, shake and/or vortex until the gel has dissolved.
   4. If the DNA is <300bp add 250uL of isopropanol
   5. transfer into the Zymo column inside a collection tube (small clear guys)
   6. spin through, discard waste.
   7. Add 200 uL of PE buffer (which is basically 70% ethanol)
   8. spin through, discard waste.
   9. Add 200 uL of PE buffer
  10. spin through, discard waste.
  11. spin for 90 seconds, full speed to dry.
  12. elute with 8.5 uL of water into a fresh Eppendorf tube 

• Second PCR step was set up ( Cloning by PCR):

24uL ddH2O
3.3uL 10x Expand Buffer "2"
3.3uL dNTPs (2mM in each)
1uL Oligo 1, 10uM
1uL Oligo 2, 10uM
0.5uL Expand polymerase "1"
0.5uL Template DNA

• 2K55 program was used again.

sbb06

• Amplification product was retrieved and prepared for an analytical gel.
  • 3uL PCR product + 7uL loading buffer
• I ran this gel.

• My amplification product was supposed to be in lane 5. The amplification does not seem to have worked. I'll re-assemble next time..

3/1/2010

sbb02

• Prepared PCR product for analytical gel.
  • 3uL PCR product + 7 uL loading buffer

• My sample is in the fourth lane. It looks good, although there is another band that looks like it is an incomplete fragment (A+B or B+C).
• Cleaned up the PCR product using a Regular Zymo Cleanup:

The following procedure 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 33uL or 50uL reaction.
   2. Transfer into the Zymo column (small clear guys)
   3. spin through, discard waste.
   4. Add 200 uL of PE or Zymo Wash buffer (which is basically 70% ethanol)
   5. spin through, discard waste.
   6. Add 200 uL of PE or Zymo Wash buffer
   7. spin through, discard waste.
   8. spin for 90 seconds, full speed to dry.
   9. elute with water into a fresh Eppendorf tube, use the same volume of water as the volume of the original reaction

sbb06

• Prepared reaction mixture for re-assembly ( PCA Gene Synthesis):
  • Labeled 06 Re-As (Re-assembly)

In case the first amplification fails, you can re-amplify using the first amplification as a template to direct the oligos in the second round: Recipe

   1. 37 uL ddH2O
   2. 5 ul 10x expand buffer
   3. 5 ul 2mM dNTPs
   4. 1 ul oligo mixture (100uM total, mixture of oligos after combination of 100uM stocks)
   5. 1 uL of purified assembly reaction from previous round
   6. 0.75 ul Expand polymerase 

Program

   1. 2 min initial denature at 94oC
   2. 30 sec denature at 94oC
   3. 30 sec anneal at 55oC [This should be the overlap temp of your oligos - vary as needed]
   4. 30 sec extension at 72oC
   5. repeat 2-4 30 times total 

Then re-do the amplification step. You can iterate these until you get a full-length product. 

• Also re-did the first assembly step from scratch (in case something went wrong along the way).
  • Labeled sbb06 S.O. (start over)
  • This one runs on the same program as the one above.

OK, so you've got a bunch of oligos, now what? First, use this recipe and program to do initial assembly of the oligos (do a separate one of these reactions for each chunk you're assembling):
Recipe

   1. 38 uL ddH2O
   2. 5 ul 10x expand buffer
   3. 5 ul 2mM dNTPs
   4. 1 ul oligo mixture (100uM total, mixture of oligos after combination of 100uM stocks)
   5. 0.75 ul Expand polymerase 

• Both PCR products will be ready next time.

3/3/10

sbb02

   2. put in ependorf tube and add 600uL of Zymo ADB buffer (brown bottle).
   3. heat at 55, shake and/or vortex until the gel has dissolved.
   4. If the DNA is <300bp add 250uL of isopropanol
   5. transfer into the Zymo column inside a collection tube (small clear guys)
   6. spin through, discard waste.
   7. Add 200 uL of PE buffer (which is basically 70% ethanol)
   8. spin through, discard waste.
   9. Add 200 uL of PE buffer
  10. spin through, discard waste.
  11. spin for 90 seconds, full speed to dry.

sbb06

• Performed a Small-Frag Zymo Cleanup.
• Prepared two identical reactions - one for re-amplification after re-assembly and the other for amplification after starting over:
  • I did the second one to get a head start in case re-amplification doesn't work and I did something wrong.

For the amplification reaction, do a normal phusion program with 1 ul of the cleaned up assembly reaction as template, and using the outermost oligos for the chunk. That is:
Recipe

   1. 1 ul each outer oligo (10 uM)
   2. .5 ul phusion

3/10/10

sbb02

• Plate was contaminated. (Probably due to contaminated LB)
• Mini-Prepped according to Macherey-Nagel Miniprep protocol:

MINIPREP (1mL - 5mL) Procedure for Plasmid DNA Purification

    * Pellet the cells (for individual cultures) 

   1. Pellet around 1.5 mL to 3 mL saturated culture by spinning full speed, 30 seconds.
   2. Dump supernatant, repeat to pellet another 1.5 mL (for a total of 3 mL if desired) 

    * Pellet the cells (for 24-well blocks) 

   1. In 327, weigh the block on the scale, fill a dirty block with water to the same weight
   2. Use the Allegra centrifuge to spin at 5500rpm for 4 minutes
   3. Dump supernatant
   4. You will need to transfer the cells to microcentrifuge tubes after resuspension in A1 in the alkaline lysis section below 

    * Do an alkaline lysis 

   1. Add 250uL of A1 buffer into each tube. Resuspend the cells using a vortexer.
   2. Add 250uL of A2 buffer (a base that denatures everything and causes cells to lyse). Gently mix up and down. Solution should become clearer.
   3. Add 300uL of A3 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.
   4. Spin in centrifuge at top speed for 5 minutes.
   5. Label columns with an alcohol-resistant lab pen. 

    * Purify DNA on a column 

   1. Pour liquid into columns, and place the columns into the centrifuge. Spin at full speed for 15 seconds.
   2. Dump liquid out of the collectors under the columns (the DNA should be stuck to the white resin)
   3. Wash each column with 500 uL of AW buffer.
   4. Spin in centrifuge at full speed for approximately 15 seconds, then flick out the liquid again.
   5. Wash with 750uL of A4 buffer (washes the salts off the resins).
   6. Spin in centrifuge at full speed for approximately 15 seconds and flick out liquid again.
   7. Spin in centrifuge at full speed for 90 sec to dry off all water and ethanol.
   8. Label new tubes and put columns in them.
   9. Elute them by squirting 50uL of water down the middle of the column (don't let it stick to the sides).
  10. Spin in centrifuge at top speed for 30 seconds.
  11. Take out columns and cap the tubes.
  12. Clean up - note the A1 buffer is stored at 4degC and all the rest at room temperature.
