All in all this doesn't matter, because parts which are in iGEM standard can be inserted and therefore they will deliver the lacking NgoMIV restriction site. Further on this could be an advantage because after digestion the fragment which is cut out can be better detected in the gel. | All in all this doesn't matter, because parts which are in iGEM standard can be inserted and therefore they will deliver the lacking NgoMIV restriction site.

pAAV_RFC25_MCS -> problem
Investigators: Anissa, Bea, Melanie, Christian L.
Comment: Continue with Mini-Prep and test digestion of pAAV_RFC25_MCS
Mini-Prep and test digestion have been performed:
Problem: Designed oligos (MCS_RFC25) for altering the MCS of the pAAV_MCS vector cannot be used.
Two startcodons are in the MCS.
The two startcodons are not in the same open reading frame (ORF). Therefore two proteins will be produced. The Gene of Interest and the short peptide (30 aa).
The idea of the oligos was to ligate the oligos into the pAAV_MCS vector. The oligos contained two overhangs which correspond to the sequences of the two restriction sites ClaI and BglII:
The pAAV_MCS vector was digested with ClaI and BglII and then we ligated the oligo and the vector. Problem was that we did not notice that the overhang of ClaI and the sequence of EcoRI of the MCS_RFC25 resulted in another ATG startcodon.
Possible Solutions:
- first: modify MCS with ordered oligos of Sven (shorter MCS which cannot be used for pEX)and clone mVenus
- Perform site-directed-mutagenesis (QuikChange from Stratagene)
- Order new MCS-oligos and consider that no new ATG is produced. For example: add another base between ClaI overhang and EcoRI sequence. -----ATXG---- This solution is the more possible one we are going to perform.

Comments:
Many things went wrong today!
- Glycerol stocks must be vortexted!
- Check mini-prep buffers - especially buffer PE (needs to contain ethanol!)
- Always check volumes - try to estimate if volume makes sense (check pipettes!)
- Don't discard bacteria cultures until glycerol stocks and mini-preps are successfully done!!!
Today's conclusion: Better ask 2 times than do something wrong without asking!!!
Site-directed mutagenesis of pAAV_iGEM-MCS (PstI)
Quickchange site directed mutagenesis:
PCR reaction:
- 2.5 µL 10x Pfu Ultra II buffer
- 0.5 µL template (therefore the a 1:20 dilution of the pAAV_iGEM-MCS (433 ng/µL) was prepared) = 10.825 ng
- 0.56 µL primer 1 (of 1:10 dilution)
- 0.56 µL primer 2 (of 1:10 dilution)
- 1 µL DMSO (primers form very strong secondary structures)
- 0.5 µL dNTP
- 18.88 µL dH2O
- 0.5 µL PfuUltra II fusion (1.25 U)
-> end volume: 25 µL
PCR program:
1 x : 2' 95°C (HotStart polymerase)
20 x : 30 s 95°C -> 1' 55°C -> 5' 68°C
1 x : 4°C (over night)

Cloning of mVenus_YFP into pAAV_iGEM-MCS, continuation of site-directed mutagenesis
Investigators: Kira, Jessy, Hanna, Achim
Analysis of iGEM-MCS sequence (RFC25 without EcoRI and NotI):
The alignment with the theoretical pAAV_iGEM-MS delivered a "C-deletion" within the NgoMIV restriction site. Due to that the pAAV_iGEM-MCS lacks this site. We controlled the bill of delivery and noted that the deletion must be GATC's fault.
All in all this doesn't matter, because parts which are in iGEM standard can be inserted and therefore they will deliver the lacking NgoMIV restriction site. Further on this could be an advantage because after digestion the fragment which is cut out can be better detected in the gel.

No pAAV_iGEM-MCS_w/oPstI transformed bacteria (site-directed mutagensis) grew on the ampicillin agar plates over night!
Experiment is conducted again, guided by Toby (Thanks a lot!!!).
Further on the cloning of mVenus-YFP into pAAV_iGEM-MCS seemed to fail:
Only on the agar plate cotaining the bacteria transformed with the "vector_oben" ligation, which actually should be the "wrong" ligation (gelextraction of a band which contained fragments that were too large, see picture in lab journal), revealed colonies. Therefore this experiments is also conducted one more time, guided by Sven (thanks also a lot!!!)

Comments: Digestion of P34.2 delivered just one fragment size, revealing that - as expected after sequencing (C-deletion: no NgoMIV site in iGEM-MCS) - there was just one NgoMIV restriction site in the vector. In contrast to that the digestion of P34.3 and P34.4 delivered two bands - whereas the band of the smaller fragments looked like a smier. Because of this obscure and non-satisfying results (besides our assumption that there's something wrong with the marker :) )we decided to sequence the P34.3 vector:

- volume (H2O) = 25.75 µL
Results (15.06.): Unfortunately just ~ 300 bp were sequenced.
To do: Therefore more primers have to be designed in order to sequence the whole ~2000 bp TK-GMK fusion construct!
Cell culture
AAV 293 and HT1080 Cells have been splitted and plated out on 10 cm dishes for transfektion. The Cells were accounted by using the Neubauer-Meteringchamber. After harvesting by following the standard protocol the pallet have been resuspendiated in 15ml of DTT medium. 2,5µl of this cell suspension have been mixed with 47.5µl of trypan blue.
We counted 12,5x 10^6 cells/ml for the T293 AAV cell line and 10x10^6 cells /ml for the HT1080 cell line.
The AAV 293 cells have been plated out on four dishes with 250µl of the cell suspension, on one plated with 1ml and on another dish with 1.5ml. note that that the date is wrong on the plates and the flasks! Cells have been already plated out on the 14th. of June.
We also seated two flasks one for each cell line. Therefor we used 1ml of the HT1080 cell suspension and two ml of the the AAV293 cells.

Primer designing: VP1 primer for pKEX forward/reverse
Investigator: Volker
The construnts that we receieved from PD Dr. Kleinschmidt (DKFZ) are mainly in the pKEX backbone. The sequences of the backbone and the inserts are not availible, for this reason we decided to sequence the constructs. The first step is to sequence from one construct into the backbone. In the second step we will designe primers that bind in the backbone and point into the direction of the insert.
These primers will then be used to sequence the inserts of all the constructs.
Forward primer pKEX in VP1 from bp 4124 to 414
- VP1 primer for pKEX forward: 5' - CAACAAGTCTGTTAATGTGGAC - 3' 22bp; TM: 50°C; CG% 41%
Reverse primer pKEX in VP1 from bp 2081 to 2100
- VP1 primer for pKEX reverse: 5' - GTGGGCCAGGTTTGAGCTTC - 3' 20bp; TM: 54°C CG%: 60%
The amplicon that should be produced by the primers is 199 bp long.
Primer designing: CMV_forward/reverse_qPCR
Investigator: Volker
Primers for the titering of the CMV region from the literature [Rohr et al., 2002] and [Rohr et al., 2005] were compared and analysed.
The sequences from 2002 showed a differce in one nucleotide compared to the other primer and to our sequence. For this reason the second set [Rohr et al., 2005] was ordered.
- CMV_forward_qPCR: 5' - GGGACTTTCCTACTTGGCA - 3'
- CMV_reverse_qPCR: 5' - GGCGGAGTTGTTACGACA - 3'
These primers will be used in a quantitative PCR assay with Sybr-green to measure the genomic titer and the infectious titer of the viral particles we will produce in the future.
Ordering of required reagents:
Investigator: Volker
- Nuclease S1 was ordered from Promega (10000Units for 36,00€)
- Proteinase K was ordered from Sigma (5mg for 31,30€; BioUltra, ≥30 units/mg protein, lyophilized powder)
These reagents are required for the procedure to determine the genomic and the infectious titer.

- pHelper
- pAAV_RC
2)
- pAAV_iGEM_mVenus_YFP (glycerol stock B33, P38) P38 (we dont know if P39 has the correct sequence!)was used because the amount of P39 was not sufficient enough for four Transfections!
- pHelper
- pAAV_RC
Plasmid concentrations:
pAAV_RC: 1 µg/µl
pHelper: 280 ng/µl

pAAV_iGEM_mVenus_YFP, P38: 179,75 ng/µl
Cellculture clone 1 and 2 were transfected with P39. Cellculture clone 3 and 4 were transfected with P38.
Deviations from the standard protocol (currently incomplete): We could only pipet 3,3 µg (instead of 10 µg) from each of the 3 plasmids into the 15 ml falcons due to insufficient amount of plasmid.
Adrian tried to examine the precipation of the CaCl2+ DNA Clusters. We have to optimize the pH of our 2xHBS at the moment it is 11.12
Theoretical: Digestion of pAAV_MCS for PCR to design ITR BioBrick

- Digest vector in order to obtain two fragments which contain the left and the right ITR respectively.
- Separation (Agarose-gel) and gel extraction of fragments
- Perform PCR with iGEM-Primers (forward primer contains EcoRI and Xbai; reverse primer contains SpeI and PstI)
- to do:
- design primers
- digestion of pAAV_MCS etc.

Splitting of HT1080 and AAV-293 cells, Seeding of HT1080 cells
Investigator: Hanna
HT1080:
- Cells showed 80 % confluence
- Cells were washed with PBS, detached with Trypsine
- 10 mL DMEM was added, cell suspension was centrifuged for 5 minutes at 200 g.
- Supernatant was discarded, pellet was resuspended with 8 mL DMEM.
- Cells were counted: 47.5 µL Trypan blue (stains dead cells) and 2.5 µL cell suspension were mixed and applied onto a Neubauer counting chamber -> 2.2 x 20 x 10^-4 cells per mL
- Therefore 27 µL of the cellsuspension was added to each 3 mL DMEM in the 6-well plates. -> 2 6-well plates were prepared for transduction!
- Further on cells were splitted: 110 µL cell suspension was pipetted into 2 75T flasks each containing 20 mL DMEM and stored in the 37°C incubator.
AAV-293 cells:
- Cells showed ~ 50% confluence
- Cells were splitted following the standard protocol.

Sequencing results of pAAV_RFC25
Investigators: Adrian, Bea, Hanna
sequenced sample: pAAV_RFC25 clone 2 (P43)
used primer: GATC_std_pTeSp-1.ab1
The alignment with the theoretical construct showed, that there's a exchange of one base in the RFC25-multiple cloning site. This substitution leads to the deletion of the SpeI restriction site.
Therefore we checked the order sheet (everything OK!).
We sent the second clone (P42) for sequencing (Hanna).
- V(Plasmid) = 6.5 µL
- V(H2O) = 23.5 µL
- Primer: pTESP-1

Continuation of ITR PCR
Investigators: Hanna, Chris W., Adrian
- Analytic gel was run: 1.7 µL loading dye (6x) was added to 8.3 µL of each sample (left ITR: 5 µL DMSO + 10 µL DMSO; right ITR: 5 µL DMSO + 10 µL DMSO).
- 110 V, 35 minutes
- No ITr bands were detectable - just 2 weak "primer-bands"
Conclusion: PCR didn't work. Because of that new primers were designed and ordered (Achim), which are longer and posses therefore higher annealing temperatures.

We found some interesting literature which points out that introns have an influence on the eucaryotic gene expression on DNA and RNA level. Next steps are going to be the designing of the beta-globin intron and maybe further analysis of the other mentioned introns. Maybe two or three more introns can be ordered.

hGH sequence
Investigator: Hanna
- orientation in pAAV_MCS is reverse annotated, but in the same orientation as in human growth hormone I gene!
- Blast and alignment with other expression vectors and the human growth hormone I revealed that Stratagene annotated 1 bp too much
- "A common feature of mRNA in higher eukaryotes (but not in yeast) is the presence of the highly conserved sequence AAUAAA in the region from 11-30 nucleotides upstream of the site of poly(A) addition. (...) The signal is needed for both cleavage and polyadenylation." (Genes VIII, Lewin, P. 720)
- good news: There're no iGEM restriction sites in the sequence (RFC25)
- Conclusion: Instead of ordering the whole sequenc in iGEM standard it would be probably easier (and cheaper) to perform a PCR.
- Done: Oligos were designed for PCR!
ITRs: new strategy
Investigator: Hanna
Plan:
- Digest pAAV_MCS with AlwNI. Result: one large fragment containing the left ITR + a small fragment containing right ITR.
- Digest both fragments with NotI and PstI.
- Hybridize oligos containing RFC10 restriction sites (designed by Hanna), ligate them via intermediate steps (ligating into a vector) with ITRs . Comment: One oligo posseses a blunt end - therefore "intermediate step-vector" needs to be digested with an enzyme producing a blunt site.
- Done: Oligos were designed. Need to be checked!

Investigation of the Kleinschmidt sequencing
Investigator: Volker
The sequencing of den unknown backbone pKEX revealed that the construct VP1ex from the DKFZ seemed not to contain a regulatory region for the expresion of the VP1 ORF, but in the backbonesequence there were some standard primers from GATC that could be used to sequence the insert of all expression constructs.
This sequencing was done at the 26.06.2010. The read into the construct VP1 showed a long homologous region with the ORF of VP1 where as the sequencing of VP2ex and VP3ex did not show a homologous region with the ORFs of VP2 and VP3.
The test weather primers of GATC bind to the unknown region gave a positive hit in both constructs with the primer GATC_std_CMV_f. This primer is specific for the sequence of the CMV promoter. After this indice the sequences VM_2 26.06. -pBR1.ab1 and VM_3 26.06. -pBR1.ab1 were aligned with the sequence of the CMV promoter provieded in the stratagene kit in the plasmid pAAV-MCS. The majority of the sequence fitted well with CMV promoter as indicated in the image in purple. At the 5' end of the CMV promoter there were some missmatches in the alignment indicated in yellow.
The fact that VP2ex and VP3ex contained a CMV promoter element which was not included in VP1ex was unexpected. The sequencing with the standard primer GATC_std_CMV_f which binds at the 3' end of the CMV promoter and will probably sequence the ORF of VP2ex and VP3ex was ordered.
