*transformation of Aa and Tt into BL21de3 --> 37°C o/n
*ordered oligos from sigma-aldrich - for Fok control
- for AGOs
- new 4mer, 8mer and 12mer Linkers
*order from Fermentas (5th floor) - NTP R0481
- T7 RNA Polymerase EPO111
- RiboRuler RNA Ladder High Range SM1823
*poured LB-Kan plates --> cold room
*hybridized Fok-control oligos 1 and 2 and M13 DNA -> digested DNA with Fok -> made analytical gel
*Made a new updated 3d model of our enzyme.
-aligned manually dna to make it bigger
-added Fluoreszin/lipocalin structure to model
-added digoxigenin/lipocalin structure to model
-measured distances from fok parts to lipcalins to estimate linker length: probably 5 AA are enough.
-found out positions for oligo-tags fluoresceine and digoxigenin by visual inspection
-found company [http://www.purimex.com/de/index.htm] that can tag oligos in the middle
-created templates for oligos: 3variations: dioligo end tags, dioligo end+middle tag, monooligo end+middle tag. see picture
pictures:
color code:
-green: fokI active domains
-pink:active AA/base where fok cuts
-yellow: possible placed to tag oligo
-red dna:oligo
-blue dna: dna that is to cut
-white:digoxigenin+lipcalin
-turquoise: fluoresceine+lipocalin

we may need to use diologoA on ice, because it might be fragile because so short.

-the expression of the Fok constructs could be on wednesday. We should do a 2 liter expression with His-Dig-Linker-Fok(active) and with His-FluA-Linker-Fok(inactive), therefore we need schikanekolben, places on the shaker, LB-medium, IPTG and Antibiotics (these things should be prepared on monday)

2eppis of each line. Cells from Trafo from 20.08.09 were pelleted down, supernatant removed.
Then plasmid purification used QIAprep Spin Miniprep Kit:
All centrifugation steps are carried out at 13000 rpm
0. Centrifuge cells at 8000 rpm for 3 min; Discard supernatant
1. Resuspend pelleted bacterial cells in 250µl Buffer P1 and transfer to a microcentrifuge tube.
2. Add 250 µl Buffer P2 and mix thoroughly by inverting the tube 4-6 times.
3. Add 350 µl Buffer N3 and mix immediately and thoroughly by inverting the tube 4-6 times.
4. Centrifuge for 10 min at 13000 rpm in a table-top microcentrifuge.
5. Apply the supernatant (from step 4) to the QIAprep spin column by decanting or pipetting.
6. Centrifuge for 30-60 s. Discard the flow-through.
7. Recommended: Wash the QIAprep spin column by adding 0.5 ml Buffer PB and centrifuging for 30-60 s. Discard the flow-through.
8. Wash QIAprep spin column by adding 0.75 ml Buffer PE and centrifuging for 30-60 s.
Here a mistace happened, since I added PE buffer that wasnt diluted in alcohol to probes pMA+StrepFluA, pEX Klon 100, 1. I removed it
trough vacuuum pump and added the correct. However results are impaired.
9. Discard the flow-through, and centrifuge for an additional 1 min to remove residual wash buffer.
10. To elute DNA, place the QIAprep column in a clean 1.5 ml microcentrifuge tueb. Add 50 µl elution buffer (EB) to the center of each QIAprep spin
column, let stand for 1 min, and centrifuge for 1 min.
Results of Plasmid Prep: (insert Nanodrop data here)
*Results of Sequencing: - pEx_CAT 2.2 clones 1 and 2(plasmid prep of 19.08.09) positive

- pEx_HisFluA clone 1 was negative (it it turned out to be His-Tag_Fok)
- pEx_StrepFluA clone 1 turned out to be His-Tag_FluA -> it's now renamed to pEx_HisFluA
- pMA_Short-Linker was positive but vector didn't match with pMA
