*hybridization of M13 DNA ss and the fokcontrols in equal relations
*made SDS gels --> 4°C
*SDS gel of protein expression (pEx-His-FluA-SplitLi-Foki) from 28.08.09 [[Image:Freiburg09_010909_pg_pExHisFluASplitLiFokIvom2808_waehrend_expression012.jpg|none|thumb|SDS-Gel; pExHisFluASplitFoki; Lanes: NEB prestained protein marker, t0 (before induction), t1 (1 hour after induction), t2 (2 hours after induction), t3 (3 hours after induction), t4 (4 hours after induction)|400x400px]] [[Image:Freiburg09_010909_pg_NiNTA_pExHisFluASplitLiFokIvom2808011.jpg|none|thumb|SDS-Gel; pExHisFluASplitFoki ; Lanes: NEB prestained protein marker, Elution fraction 1 (after NiNTA-column), Elution fraction 2, Elution fraction 3, Elution fraction 4, Elution fraction 5, Elution fraction 6, Elution fraction 7, Elution fraction 8, Elution faction 9 |400x400px]] Lane 4 showed some strange bands, so we repeated the gel

*made 1l buffer for AGO cleavage assay: 100mM NaCl, 10mM HEPES, 5mM MnCl2, pH 7.5
*came up with idea for new BioBrick standart that would allow making fusiun proteins via "mega primer" pcr technic with only a Threonine as a scar and thereby skipping the cloning procedure: [[Image:Freiburg 09 Superstandard.jpg|none|thumb||400x400px]] The new restriction enzyme would be AcuI, that for example has no cutting site in M13mp18 and just one in pET28 and two times in pMAL-p5X core vector
AcuI cuts 14/16 bases away from its recognition sequence end would thereby cut off the whole BB prefix and most of the BB suffix (with just AC left)
*purification of pExHisFluASplitFoki via Ni-NTA column
*inoculation of pExHisFluASplitFoki36GSlinker
*starter cultures of - pExHisDigSplitFoka
- pExStrepDigSplitFoka

02.09.09, Manu, Hannes, Christoph, Gerrit, Laura, Isabel

*Inoculation of expression culture - pExHisDigSplitFoka
- pExStrepDigSplitFoka
in 2 times 1 liter each at 28°C , 118rpm
-> induction of expression at OD 0,4, harvesting 4 hours later
-> centrifugation at 4000 rpm, 4°C, 20 min -> put pellets in -80°C freezer
*cleaning of Ni column with 15 ml water and 10 ml Ethanol (20%)
*plasmid preparation of pExHisFluASplitFoki36GSlinker, glycerol stocks and sequencing
*repetition of SDS gel of eluate fractions (pExHisFluASplitFoki) see picture... -> fractions 2 and 3 showed the probable Foki fusion protein and were united and dialysed [[Image:Freiburg09_020909_pg_pExHisFluASplitLiFokIvom2808_repeat013.jpg|none|thumb|SDS-Gel; pExHisFluASplitFoki ; Lanes: NEB prestained protein marker, Elution fraction 1, Elution fraction 2, Elution fraction 3, Elution fraction 4, Elution fraction 5, flow through fraction 1, flow through fraction 3, washing fraction 1 (250mM imidazole), washing fraction 3|400x400px]]
*order of new short, middle and long linkers with XbaI, NgoMIV and AgeI restriction sites
*made binding, washing and elution buffer (1 liter each) again for His/Ni purification
*prepared 2 liters of dialysis buffer (30mM NaCl, 20mM Tris/HCl, pH 7,4)
*centrifugation of the expression culture (20 min, 4000 rpm, 4°C), stored pellets at -20°C
*started dialysis over night with 200 ml dialysis buffer and 3 ml protein solution (elutions 2 and 3 were combined), stiring at 4°C

Meeting

*Kristian introduced GBM, please add your data to the list if you want to join the group founded for iGEM
*Fok - the tagged Oligo's arrived during the absence of Kristian and stayed one week in his mail box at room temperature. Christoph wanted to find out, how this affects the DNA
- we should repeat the Fok cutting assay with M13 dsDNA and change the origami-programm to stop at 37°C (instead of 20°C)
- new Oligo's for the cutting assay must be ordered with a length of 60 bp

- dialyse the his-tag purified protein solution to get the right ion concentrations for a ion exchange chromatography
- with the his-tag purified and dialysed protein solution we must do some tests: freeze it, thaw it and measure the stray light(photometer)
- prepare aliquots of the protein solution
- do a purification via ion exchange chromatography (MonoQ, positive charged)
- try a first cutting assay with our construct
- confirm the Oligo-Protein-interaction with a fluorescence or absorption measurement (we have to do some research on this)

*Fok-Phage Display - we want to assemble the different parts with a PCR with overlapping primers (including the GS-linker). We should use a mix of Taq and a proof reading polymerasy and have a maximum cycle number of 20 to keep the mutations as low as possible
- order parts at Mr.Gene with iGEM restriction sites
- we must plan the PCR-primers!!!

*AGO - first try to cut single strand DNA

*book rooms in a hotel (Anika wanted get some info about the hotels)

03.09.09, Manuel, Hannes, Christoph, Gerrit, Timo

*Hybridization of M13 ssDNA with FokKontrolle 2(1:100) and 3(1:100 dil)

Restriction_enzyme_1 : 1 µl AgeI from NEB KuKlabstock
Restriction_enzyme_2 : 2 µl PstI from NEB KuKlabstock

*Gel extraction of pEX_His_FluA_Split_Foki_36GSli (prep 02.09.09 rest4 tube3)

*Ligation of vector:pEX_His_FluA_Split_Foki_36GSli(prep 02.09.09 rest4 tube3) with insert:Foka(Gelex 17.08)

*Conzentrated AGO 5x via Vivaspin to final conzentration of 3µM (2ml)
*Exchanged buffer of 900µl of Aa AGO solution via dialysis
*Started PCR procedure to create Aa AGO as an BB part via megaprimer technic
*His-Dig purification of protein expression from 02.09.09 (pExHisDigSplitFoka)
*SDS gel of His-Dig purification HisDigSplitFoka [[Image:Freiburg09_040909_pg_HisDigSplitFoka_vom030909015.jpg|none|thumb|SDS-Gel; pExHisDigSplitFoka ; Lanes: NEB prestained protein marker, Elution fraction 1, Elution fraction 2, Elution fraction 3, Elution fraction 4, Elution fraction 5, Elution fraction 6, flow through fraction 1, flow through fraction 3, washing fraction 1|400x400px]]
*changed dialysis buffer, again with 200 ml (10:00 o'clock)

04.09.09, Manu, Hannes, Christoph, Laura, Sarah,Timo

*Ordered additional Oligo for M13mp18 cleavage with AGO: "Oligo A4" AAGTTTTTTGGGGTCGAGGTG should allow the Aa Argonaute protein to cut the M13mp18 ssDNA behind base 100. combination with A1 (cuts at 3100) should result in two destinc bandes on the gel with a 1:2 size ratio
*AGO: over night dialysis to exchange buffer to the "AGO assaybuffer". NanoDrop: 0.575 mg/ml --> 6µM in ca. 1.2 ml buffer -> -20°C freezer
*AGO cleavage assay with M13mp18 ssDNA was roughly performed following the original RNA assay (Ma et al.):
15µl of the Aa Argonaute protein in the "Ago assay buffer" were incubated 30 minutes with 1µl of 100µM of the guideoligo A1 (ACAACCATCGCCCACGCATAA)at 55°C
Then 20µl of M13mp18 ssDNA (248ng/µl)was added and incubated for 30 minutes at 55°C
One half of the solvent was treated with proteinase K solution, the other was untreated added to the agarose gele --> we obtained 2 bands which might be the circular M13 DNA and the linear M13 DNA [[Image:Freiburg 09 AGO M13 verdau 45min.JPG|none|thumb|Agarose gele of AGO M13 digest; Lanes: Marker:1kb ladder, AGO M13 digest, AGO M13 digest treated with Proteinase K, untreated M13 ssDNA|400x400px]]
On lane two there is a clearly visible bandshift. The band on the very bottom of lane three is most likely the guide oligo that was released when the AGO was destroyed by the proteinase.
Next week we will do another assay with two guide oligos (A1 and A4) that should result in two distinct bands and thereby allow as to exclude the possibility that the bandeshift is due to AGO bound to the targed ssDNA
*AGO PCR to craeat an Aa AGO BB part failed and will be repeated on Monday

06.09.09, Hannes

*Inoculation of: - BL21de3 pEx-StrepDigSplitFoka

*Starter culture of pEx-His-Flua-Split-Foki(amp plate of 25.08.09)in BL21DE3 (200 ml LB + amp)
*Hybridisation of long, middle and short linker
*pEx His-FluA-Split-Foki-36GSLi-Foka is now called FokM [http://www.molbiotech.uni-freiburg.de/iGEM/wiki2009/index.php/Fok_monomer Sequenz]
*Transformation of FokM into BL21 de3 gold

08.09.09, Manu, Gerrit, Christoph, Sarah, Anika, Hannes, Laura, Isabel, Julia

*made LB Agar
*poured amp plates (3 plates left)
*ligation of short, middle and long linker (hybridized at 07.09.09) and pMA vector (gelex from 27.08.09)
*ligation of short, middle and long linker (hybridized at 07.09.09) and pMA_Foki (gelex from 28.08.09) and pMA_Foka (gelex from 27.08.09)
*made SDS gel of collected pellets (T0-3) from expression of StrepDigSplitFoka and HisDigSplitFoka aim: to see if induction of expression of fusioned protein was successful [[Image:Freiburg09_090909_pg_HisDigSplitFoka_SDS017.jpg|none|thumb|SDS-Gel; pExHisDigSplitFoka ; Lanes: NEB prestained protein marker, expression fraction T0, T1, T2, T3, T1, T2, T3|400x400px]] [[Image:Freiburg09_090909_pg_StrepDigSplitFoka_SDS016.jpg|none|thumb|SDS-Gel; pExStrepDigSplitFoka ; Lanes: NEB prestained protein marker, expression fraction T0, T1, T2, T3, T1, T2, T3|400x400px]]
*Stripping of Ni-NTA column
*made starter culture (300ml LB+Amp+1%Glucose) with pEXHisDigSplitFoki in BL21de3
*Made gradient PCR (+-5 in first 10 cycles; +-2.5 in last 14 cycles) to generate BB Aa AGO part. Therefor optimised pcr protocoll and made an additional approach using DMSO

09.09.09, Gerrit, Christoph, Sarah, Isabel, Anika, Hannes, Laura, Max, Julia, Dieter

*expression of pExHisFluASplitFoki in 6 times 1 ml LB and Amp - pellets were taken at T0 (time of induction with IPTG), T1, T2, T3, T4
- at the end culture was centrifuged down at 4000rpm, 20 min, 4°C
- pellets frozen in -80° C

* Repetition of AGO cleavage assay, using oligos A1 and/or A4 to determine whether bandshift was due to AGO bound to the DNA or cleavege of the ssDNA target--> Agarose gel revealed several promising bands (see picture). Results have to be dicussed yet.
* test digestion of FokM shows that vector and insert are to small
* test expression of FokM aborted
* new cloning of FokM has to be done tomorrow
*new measurement of concentration of HisFluASplitFoki (dialysed at 03.09.09)
*Agarosegel of yesterdays gradient PCR again showed none of the expected bands.
-> Gel of the used template "Aa AGO in pET28a 27.08.09 1" revealed an unexpected strong band at app. 20kb. pET28a with the Aa AGO as an insert should be 7.5kb in size. No such band was observed.
* Therefore a new PCR was started using the original optimised PCR protocol (first annealing temperature 55°C, second 65°C) using the sample "Aa AGO in pET28a 27.08.09 2" as a template
*measurement of fluorescence of FluA marked oligo, protein, and oligo and protein (quenching)

+<br>*made starter culture (300ml LB+Amp+1%Glucose) with pEXHisDigSplitFoki in BL21de3
+<br>*Made gradient PCR (+-5 in first 10 cycles; +-2.5 in last 14 cycles) to generate BB Aa AGO part. Therefor optimised pcr protocoll and made an additional approach using DMSO

+<h3>09.09.09, Gerrit, Christoph, Sarah, Isabel, Anika, Hannes, Laura, Max, Julia, Dieter</h3>
+<br>*expression of pExHisFluASplitFoki in 6 times 1 ml LB and Amp
+- pellets were taken at T0 (time of induction with IPTG), T1, T2, T3, T4<br>
+- at the end culture was centrifuged down at 4000rpm, 20 min, 4°C<br>
+- pellets frozen in -80° C<br>
+<br>* Repetition of AGO cleavage assay, using oligos A1 and/or A4 to determine whether bandshift was due to AGO bound to the DNA or cleavege of the ssDNA target-->  Agarose gel revealed several promising bands (see picture). Results have to be dicussed yet.
+<br>* test digestion of FokM shows that vector and insert are to small
+<br>* test expression of FokM aborted
+<br>* new cloning of FokM has to be done tomorrow
+<br>*new measurement of concentration of HisFluASplitFoki (dialysed at 03.09.09)
+<br>*Agarosegel of yesterdays gradient PCR again showed none of the expected bands.<br>
+-> Gel of the used template "Aa AGO in pET28a 27.08.09 1" revealed an unexpected strong band at app. 20kb. pET28a with the Aa AGO as an insert should be 7.5kb in size. No such band was observed.
+<br>* Therefore a new PCR was started using the original optimised PCR protocol (first annealing temperature 55°C, second 65°C) using the sample "Aa AGO in pET28a 27.08.09 2" as a template
+<br>*measurement of fluorescence of FluA marked oligo, protein, and oligo and protein (quenching)

-<br>*Made new "AGO BB PCR" this time just using the ad-on-tail-primer for the bb pre- and suffix, so that hte EcoRI site should remain. Still the same not fitting bands were obtained-> the problem might be caused by multimerising of the primers, even so we were not able to predict any of tose using vectir nti or compairable programms...
-<br>* AGO assay using different targets-> were not able to reproduce the presumed cutting event from Saturdays assay probably due to the lower DNA concentration
-<br>* Made ELISA with strep-biotinylated target oligo coated surface-> no binding of AGO bearing phages was detected using anti-M13 HRP and ABTS
-<br>* Made test panning just like the ELISA above and eludet with TBS-MnCl2 (5mM), then TBST-MnCl2 (5mM) and then with DNase I
