... and following ligation (2,5 µl Insert, 5,5 µl vector, 1 µl T4 DNA Ligase, 1 µl T4 DNA Ligase Buffer (10x), 40 minutes, RT) were performed according to the standard protocol. After the transformation (with XL1B) the cells were plated and put into the 37°C room.

Two additional transformations were performed with ligations from Volker labeled: "ligation viral brick 453 empty" & "viral brick 587 empty". <br>

Unfortunately the digestions had to be reapeated because i didnt switch on the current so the samples and especially the 1kb GeneRuler marker diffused.

<b>Ultrafiltration</b> <br/>

Ultrafiltration of CFP_MiddleLinker_VP2/3 containing virus particles and 587-BAP virus particles were concentrated via Vivaspin-Ultrafiltration: <br/>
 +
*20 mL virus containing cell culture supernatant was added to GE Vivaspin 20 filter and centrifuged with 4000 g at 15°C until 750 - 1000 µL was left-
 +
* 5 mL Bis-Trus buffer (pH 6) was added and centrifuged again with 4000 g at 15°C (washing).
 +
* This step was repeated 3 more times.
 +
* Membrane was carefully resuspended and cleared. Suspension was transfered to low-binding eppi and centrifuged with 10000 g for 10 minutes at 15°C.
 +
* Supernatant was transfered to new low-binding eppi and again centrifuged with 10000 g for 10 minutes at 15°C.
 +
* Supernatant was transfered to new low-binding eppi and stored at 4°C over night. <b>To do:</b> ÄKTA chromatography. <br/>

5 µL Laemmli buffer was added to 20 µL sample. Samples were incubated at 95°C for 8 minutes and loaded onto a SDS gel (10 %). SDS PAGE was performed at 90 V (collection gel) resp. 120 V (separation gel). <br/>

150. labday 15.10.2010

Cloning CFP (from P666: PSB1C3_CFP) into pSB1C3_leftITR_CMV_beta-globin (P729)

Investigator Patrick
Digestions, 2 h 10 minutes, 37 °C:

  • P666: 5 µl DNA, 2 µl BSA, 2 µl Buffer 4 (10x), 1 µl Xba, 1 µl PstI, 9 µl H2O
  • P729: 4 µl DNA, 2 µl BSA, 2 µl Buffer 4 (10x), 1 µl SpeI, 1 µl PstI, 10 µl H2O

Expected results for the 1% agarose gel:

  • P666: about 2100 and 750 bp
  • P729: about 3300 and 20 bp


Freiburg10 1015pat fertig.jpg



The gelextraction ...

P728: 11,8 ng/µl
P822: 34,6 ng/µl

... and following ligation (2,5 µl Insert, 5,5 µl vector, 1 µl T4 DNA Ligase, 1 µl T4 DNA Ligase Buffer (10x), 40 minutes, RT) were performed according to the standard protocol. After the transformation (with XL1B) the cells were plated and put into the 37°C room. Two additional transformations were performed with ligations from Volker labeled: "ligation viral brick 453 empty" & "viral brick 587 empty".

The following day the plates were checked for clones. Unfortunately there grew no clones on these two plates contrary to my plate with a a lot of clones.

For further experiments, RNA has to be translated into cDNA. The PCR was performed according to the manufacturer protocol.

153. labday 18.10.2010

quantitative real-time PCR for detection of virus titer

Investigator: Achim

  • qPCR of harvested virus particles to determine the virus titers of our different constructs
  • Total number of samples: 58

Test-digestion of pSB1C3_lITR_phTERT_betaglobin_mGMK_TK30_hGH_rITR_SDM-PstI clone 1, 2 and 3 (P877, 878 and 879)

Investigator Patrick

Check the plasmid for leftITR: 0,5 µl EcoRI, 1 µl BstEII, 7 µl DNA, 2 µl Buffer 4, 2 µl BSA, 7,5 µl H2O, 45 minutes 37°C, 45 minutes 60°C

Check the plasmid for hGH_rITR and ... : 0,5 µl AgeI, 0,5 µl PstI, 3 µl DNA, 1 µl BSA, 1 µl Buffer 4, 4 µl H2O, 70 minutes 37°C

Expected results:

  • leftITR: about 190 bp
  • hGH_rITR: about 670 bp


Unfortunately the digestions had to be reapeated because i didnt switch on the current so the samples and especially the 1kb GeneRuler marker diffused.

The second run: see above

ÄKTA Chromatography and Ultrafiltration of virus particles

Investigator: Hanna
ÄKTA chromatography with VP1up_NLS_mVenus_VP2/3 containing virus particles was conducted. Fraction 5 - 10 delivered highest protein concentrations.

Ultrafiltration
Ultrafiltration of CFP_MiddleLinker_VP2/3 containing virus particles and 587-BAP virus particles were concentrated via Vivaspin-Ultrafiltration:

  • 20 mL virus containing cell culture supernatant was added to GE Vivaspin 20 filter and centrifuged with 4000 g at 15°C until 750 - 1000 µL was left-
  • 5 mL Bis-Trus buffer (pH 6) was added and centrifuged again with 4000 g at 15°C (washing).
  • This step was repeated 3 more times.
  • Membrane was carefully resuspended and cleared. Suspension was transfered to low-binding eppi and centrifuged with 10000 g for 10 minutes at 15°C.
  • Supernatant was transfered to new low-binding eppi and again centrifuged with 10000 g for 10 minutes at 15°C.
  • Supernatant was transfered to new low-binding eppi and stored at 4°C over night. To do: ÄKTA chromatography.

SDS PAGE and Coomassie staining

Investigator: Hanna

Prior to performing Western Blot we decided to investigate running behaviour of different samples.

  • 1. Cell debris (control)
  • 2. Cell debris containing virus particles
  • 3. Concentrated virus stock (containing CFP_MiddleLinker_VP2/3)
  • 4. ÄKTA purified virus stock: Fraction 6
  • 5. ÄKTA purified virus stock: Fraction 7
  • 6. Benzonase treated, ÄKTA purified virus stock: Fraction 7
  • 7. Benzonase treated, ÄKTA purified virus stock: Fraction 8


5 µL Laemmli buffer was added to 20 µL sample. Samples were incubated at 95°C for 8 minutes and loaded onto a SDS gel (10 %). SDS PAGE was performed at 90 V (collection gel) resp. 120 V (separation gel).
Gel was put into Coomassie dye, heated for 30 seconds in microwave and incubated for 1 hours shaking.
Gel was decolorized in acetic acid (20%).
Loading plan:

Gel picture shows that concentration works :)
In addition to that one can see that the BSA bands disappear after ÄKTA chromatography.
Next step: Western Blot of ÄKTA purified virus stocks.
