Finally the colonies are growing on LB agar plates with ampicillin. The negative control does not show any colonies, the double negative does??, the positive control shows a lot of red colonies. On one of the four plates there are no colonies present, on two of them only a couple and on one a lot.

The colonies are picked and placed in LB medium with ampicillin to grow further for miniprep. Colony PCR revealed no bands.

Mini prep analysis is done with the colonies of plate 1 and 3.
Restriction analysis is done with EcoRV.

Picked colonies from the plate with the backbone of Munich (BBa_K823023) for overnight inoculation in LB medium with ampicillin. To obtain more sample of this backbone.


Inne
Did a PCR with 3 samples in duplo

Sample Primer F Primer R Annealing temp.
1 without strep tag without strep tag 78 C
2 with strep tag without strep tag 78 C
3 without strep tag with strep tag 80 C

Protocol:

amount compound
28.2 uL MilliQ
1.5 uL 5% DMSO
1 uL each dNTP
10 uL Phusion GC buffer
2.5 uL Primer F
2.5 uL Primer R
1 uL Silk template BBa_16
0.3 uL Phusion polymerase


Ran the gel 1.5% agarose using the big slots,
gel ran at 90 V for 45 minutes.
gel didn't run nice, tried to cut out bands from 2 and 3.
did gel purification
Ran 0.8% agarose gel for 24 min on 100 V
Turned out that the bands were a bit higher then 1kb


made new TBE buffer. 100ml TBE/900ml demiwater.


made the inoculation of the e.coli with the BBa_k818000 biobrick for the Delft iGEM team.
Cells inoculated in 4 ml LB liquid medium with 8 uL of stock Ampicillin
Cells are to grow overnight in a 37 C shaker.

did a Restriction digestion for Silk and Signal Sequences.

Sample componant volume (ul)
silk1 silk 4
BamHI buffer 2
BamHI enzyme 0,5
silk2 silk 4
BamHI buffer 2
BamHI enzyme 0,5
silk3 silk 4
BamHI buffer 2
BamHI enzyme 0,5
SS MotB MotB 2
BamHI buffer 2
BamHI enzyme 0,5
SS FliZ Fliz 2
BamHI buffer 2
BamHI enzyme 0,5
SS EstA EstA 2
BamHI buffer 2
BamHI enzyme 0,5
SS LytB LytB 2
BamHI buffer 2
BamHI enzyme 0,5


MilliQ was added to reach a 20 ul volume.
Incubation started at 11:00 for the signal sequences and 11:30 for the silk.
at 15:38 the restriction digestion reaction was run over a 1,5 % agarose gel with 100 v for 22 min.
no result on the gel for the sik. resulst as expected for signal sequence.
