    • Na2HPO4 - 1.35 g 　　
    • Citric acid - 0.75 g 　　
    • Distilled water - 500 ml
　(If you are making plates, use the same protocol but add 7.5 g of agar.)

Equipment 　
  • autoclave 　
  • incubator 　
  • scale 　
  • bunsen burner 　
  • flask(1l or500ml) 　
  • plate 　
  • spreader 　
  • pipet 　
  • pipet tip

Procedure 　
  1. Prepare media as outlined (add the materials as above) 　
  2. Autoclave to sterilize media(121°C　20minute). 　
  3. Streak/inoculate A.xylinum onto plates or in media. 　
  4. Incubate cells at 26°C for 2-3 days. 　
  5. If using a freeze dried source of A.xylinum, growth may take up to 4 days.

Note 　
  1. The growth of A.xylinum does not give a cloudy appearance in the media, the media will remain transparent to slightly translucent in appearance. 　
  2. The growth of A.xylinum is accompanied by the formation of a thick cellulose matrix within the media that must be removed before cells can be pelleted for a miniprep procedure. Simply vortex briefly to break up the cellulose into chunks and remove the cellulose chunks from the media with a pipette while carefully avoiding the removal of cells. 　
  3. A.xylinum will grow well at room temperature in aerobic conditions.

    • Yeast extract - 10g 　　
    • CaCO3 30g 　　
    • Distilled water - 1000 ml 　　
　(If you are making plates, use the same protocol but add 7.5 g of agar.)

Equipment 　
  • autoclave 　
  • incubator 　
  • scale

  5. If using a freeze dried source of A.xylinum, growth may take up to 4 days.

Note 　
  1. The growth of A.xylinum does not give a cloudy appearance in the media, the media will remain transparent to slightly translucent in appearance. 　
  2. The growth of A.xylinum is accompanied by the formation of a thick cellulose matrix within the media that must be removed before cells can be pelleted for a miniprep procedure. Simply vortex briefly to break up the cellulose into chunks and remove the cellulose chunks from the media with a pipette while carefully avoiding the removal of cells. 　
  3. A.xylinum will grow well at room temperature in aerobic conditions.

　Grow up a culture of E.coli

Material
  • E.coli K12strain
  • 1l of solid LB media
    • Distilled water 1l
    • LB agar (from Becton, Dickinson and Company) 35g

Equipment
  • autoclave
  • incubator
  • scale
  • bunsen burner
  • flask(500ml)
  • plate
  • inoculating loop

Procedure
  1. Prepare media as outlined (add the materials as above).
  2. Autoclave to sterilize media(121°C　20minute).
  3. Streak/inoculate E.coli onto plates or in media.
  4. Incubate cells at 37°C.

　Direct PCR

Material
  • E.coli K12 colony
  • 10µM/l forward Primer 5µl
  • 10µM/l reverse Primer 5µl
  • 10×EX taq buffer 10µl
  • 2.5mM each dNTP mixture 10µl
  • EX taq polymerase 1µl
  • milli-Q 71µl

Equipment
  • thermal cycler
  • vortex mixer
  • PCR-tubes
  • pipet
  • pipet tip

Procedure
  1. Add and mix above materials to 50μl in each PCR tubes on the ice
  2. Pick up E.coli K12 cells from its colony and add into the PCR tubes
  3. Setting tips and elongation in the thermal cycler
    • initialization :95°C 3min
    • denaturation:96°C 1min
    • annealing :55°C 5min
    • elongation:72°C 1min

      • (30cycles from 96°C 1min to 72°C 1min)

    • reaction stop :10°C

　Electrophoresis

Material
  • 1% agarose gel
    • agarose S 3g
    • TAE buffer 300ml
    • ethidium bromide 15µl
  • 1×TAE buffer
  • 10×Loading buffer 5µl
  • template DNA(PCR production)

Equipment
  • microwave
  • gel box
  • flask(500ml)

Procedure
  1. Measure out 3g agarose into a beaker with the 300ml of TAE buffer.Microwave until the agarose is fully melted(5minutes×3).
  2. Let the agarose cool on your bench until touching the bottom of the beaker with your bare hand doesn't burn you (~5 minutes for a 50mL gel). At this point add your DNA stain, e.g., ethidium bromide 15µl. The beaker will cool unevenly (surface first), so you must be careful not to cause ripples and bubbles.
  3. While the solution is cooling, seal the open edges of your gel box with one long piece of masking tape on each side. Make sure it is sealed well or the gel will leak.
  4. Pour the agarose solution into the taped gelbox. Carefuly pop or shove to the side any bubbles, put in the comb, and let it cool for about 30 minutes, until the gel is solid.
  5. If your gel is at all purple, and you are using ethidium bromide as the DNA stain, you need to decrease your concentration by at least a factor of ten.
  6. set agarose gel and add TAE buffer in gel box.
  7. mix DNA and Loading buffer and then put in well them(marker sets another well).
  8. load DNA at 100V for two third of entire(about 15minutes).
  9. image the consequence of electrophoreses.

　DNA purification from agarose gel with QIAGEN

　Material
  • QIAGEN(gel extraction kit)
    • QG buffer 300µl
    • PE buffer700µl
    • EB buffer 50µl

　Equipment
  • centrifuge
  • heating plate
  • pipet
  • pipet tip

　Procedure
  1. cut gel of electrophoreses
  2. add pieces of gel to tubes
  3. take 300µl QG buffer into tubes and dissolve at 50°C
  4. add a solution of QG buffer and gel to tubes for column
  5. centrifuge 15000rpm/1min
  6. throw “flow-thru” away and take 700µl PE buffer
  7. centrifuge 15000rpm/1min
  8. throw flow-thru away
  9. centrifuge 15000rpm/1min
  10. change tube for column
  11. add 50µl of EB buffer (aim to center of tube)
  12. centrifuge 15000rpm/1min
