  • order enzymes
  • Transformed BBa_K118016 from Kit Plate 2014 #3 well 20G into competent NEB10beta cells by heat shock (plated on LB+C)
  • gradient PCR using J04450 in pSB1C3 (#ZWDH#) as the template (diluted 1:10) primers are: #TSTV# and #FYTO# - the 10 products were put into #ES4X# and frozen

15-05-12

  • made master plates and liquid cultures (5 ml LB+C) of two BBa_K118016 clones
  • run the agarose gel of yesterdays gradient PCR products (#ES4X#) (expected length: 2070 bp)
    • PCR did not work - Discussion of potential reasons: tubes were heated to long before cycler program was started -> primers could have been digested
  • pSB1C3 gradientPCR repeated. Products stored in #18FF#

15-05-13

  • PCR products from #18FF# were digested with DpnI
  • made cryos of BBa_K118016 in pSB1C3 in DH5α (#RKD1# and #EK3S#)
  • pPrep BBa_K118016 in pSB1C3 (#F3HE# and #4D6H#)
  • purify the good pSB1C3 backbone PCR products into #6MZP# and #WHYV#
  • diluted glgA (#OB8B#), glgB 1+2 (#3XZX# and #AV9S#), Phi (#8D18#) gBlocks to a concentration of 10 ng/µl using 20 µl of ddH2O
  • CPEC assembly of #6MZP# or #WHYV# with synthesized linear DNA:

The CPEC products were stored in #XY9Y#, electroporated (1.5 µl + 25 µl) into NEB10beta cells and plated on LB+C

Note: one week later we found out that there was an error in the Excel sheet - the elongation time should have been twice as long!

15-05-14

  • send BBa_K118016 in pSB1C3 (#F3HE# and #4D6H#) into sequencing using #A9W9# and #XE3D# at 65° annealing
  • CPEC results:
construct clones next steps
BBa_K1585310 (glgA) 0 run the CPEC product on an Agarose gel
BBa_K1585311 (glgB) 5 master plates and overnight cultures

15-05-15

  • all K1585311 in pSB1C3 constructs failed - the cultures and the master plates are dark red.
  • make cryo cultures and plasmid preps of 4xK1585311 in pSB1C3
  • check PCR the prepped plasmids of K1585311 in pSB1C3 using #A9W9# and #XE3D# at 65 °C annealing and 2523 bp expected product length

We can then try the CPEC again and for glgA do restriction with E+P and ligation into digested pSB1C3 in parallel - one of them will succeed.

For that amplified the gBlocks by Phusion PCR. (20 µl reactions, 2 ng template DNA, 0'30" initial denaturation, 0'30" denaturation, 0'30" annealing) The products are in #9CRS#.

  • annotate the gel pictures and fill in the results in the table of yesterdays documentation
  • transformation of potential K1585310 in pSB1C3 (#VVRL#) into DH5α

3x 50 µl reactions with PfuS polymerase according to the cheat sheet. We use 1 µl of gBlock template (10 ng/µl) per reaction. That's 10 ng per 50 µl reaction and completely sufficient! A slight delay was caused by using the wrong dNTP mix at first. Somehow we had more master mix volume than anticipated.
