Amplification from FS_08 to FS_11_short; 6.5 kb

Gel for testing concentrations of older fragments; run at 100 V, 0.8 % gel (TAE)
Gel for testing concentrations of fragment DelG (16.07; Conditions II; after gel extraction; run at 100 V, 0.8 % gel (TAE)

Results:

  • Only a small band with conditions II was visible
  • There were no bands with the other two
  • Bands were cut out and DNA purified using QIAquick Gel Extration Kit.

lane2=Re-PCR DelG, lane3=amplification DelG (18.07), rest see DelH
Reaction
what µl
D. acidovorans DSM-39 1
FS_08: (1/10) 2
FS_11_short: (1/10) 2
Phusion flash Master Mix 10
DMSO 1

Results:

  • Amplification of DelG did not work, no product was detectable
  • PCR will be repeated at higher temperature to decrease formation of secondary structures and thereby improve binding of primers to the desired sequence

Re-Amplification from FS_08 to FS_11_short; 6.5 kb; 09-07-2013)

lane2=Re-PCR DelG, lane3=amplification DelG (18.07), rest see DelH
Reaction
what µl
DelG (09-07-2013) 4
FS_08 (1/10) 2

1 4 inf

Results:

  • Amplification of DelG was not sucessful, the Re-PCR did not yield the desired product
  • forward Primer will be reused but reverse primer changed, in order to obtain a shorter amplicon and another strategy for the Gibson Assembly

Amplification from FS_08 to FS_09; 3.3 kb

+=with DMSO, -=without DMSO; expected amplicon sizes: LP=6.4kbp, 8-9=3.1kbp, 21-09 and 20-09=8.1kbp, 22-13s=2.6kbp, AE=5.3kbp; run at 100 V, 0.8 % gel (TAE)
Amplifications of 18.07 and 19.07, cut

Results:

  • Amplification of DelG did not lead to the desired product, a small band of the desired size was visible and cut for validation and Re-PCR
  • Re-PCR will be run
