- 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!

- 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#.

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.

- measured the DNA concentrations in yesterdays purified PCR products (#BPTC#, #KONM#, #LO4N#, #TX1M#)
- gradient PCR using #TSTV# and #FYTO# on 45 ng J04450 in pSB1C3 (#ZDWH#) per 50 µl PfuS reaction mix. Annealing temperatures 65-68 °C, 1'15" elongation time. Products stored in #YDTH# - on the gel it looks like 68 °C is really good, 67.3 has multiple unspecific products, but for an unknown reason the lower temperatures did not work.
- pSB1C3 PCR product purification (#6WCN#)
- Restrictions (2x the concentration of T4 Ligase due to human error.)
- digestion of amplified glgA (#BPTC#) with EcoRI and PstI -> product is I in #CQ1V#
- digestion of prepped pSB1C3 (#CD8B#) with EcoRI and PstI -> product is V in #CQ1V#
- Ligation of 2 µl digested glgA and 2 µl digested pSB1C3
- Q5-CPEC of glgB part 1 (#KONM#), glgB part 2 (#LO4N#) and linearized pSB1C3 (#6WCN#) -> product is B in #4A4P#
- 98:0'30", 15x(98:0'10", 55:0'30", 72:2'20"), 72:10'00"
- transformation of 5 µl glgA ligation product into 50 µl home made chemically competent NEB10b + 200 µl SOC
- transformation of 5 µl glgB CPEC product into 50 µl commercial chemically competent NEB5a + 200 µl SOC
- after 60' of incubation at 37 °C the total volume of each transformation was plated on LB+C
- master plates (four clones, one clone from each transformation plate) and overnight cultures (LB+C) of K1585312 in pSB1C3 (sequencing results: #F3HE# and #4D6H# are 100 % correct)
15-05-21

- make new master plates of all remaining white colonies of glgA and some of glgB (for glgA also a few overnights?)
15-05-27
- moved master plates of glgA and B into the fridge
- cryos of glgA clones, freeze remaining culture for plasmid prep -> all glgA clones were negative on the colony PCR
- analyze sequencing results (glgA is without the insert, glgB looks good for #YHT3#, but the sequencing did not reach the center - as expected)
- prepared #YHT3# for sequencing with multiple new primers
- added 1 µl to both PCR products in #VVRL# and put it into the 37 °C room for overnight digest
15-05-28
- trash all existing glgA cryos and clones, because all of them are negative (sequencing/colony PCR)

- expected: 1535 bp

15-06-30
- we have clones of K1585312 into pSB1C3 (red-white screening)
- made master plate (6 clones) and overnight cultures (3 cultures)
15-07-01
- cryos and freezings of the three K1585312 in pSB1C3 cultures
- colony PCR on all 6 clones > clone 1 and 2 look good
