Digestions, 2 h 10 minutes, 37 °C:
-
<b>Comment:</b> Because yesterday's cloning didn't deliver a good separartion of the expected gel bands. Nevertheless ligation and trafo was performed. In order to immediately find out, whether we received successful results a colony PCR will be performed. <br/>
+
*P666: 5 µl DNA, 2 µl BSA, 2 µl Buffer 4 (10x), 1 µl Xba, 1 µl PstI, 9 µl H2O
-
Two clones were picked from each plat. In addition to that a positive (pAAV_RC) and a negative control (pSB1C3_lITR) was prepared. <br/>
+
*P729: 4 µl DNA, 2 µl BSA, 2 µl Buffer 4 (10x), 1 µl SpeI, 1 µl PstI, 10 µl H2O
-
Used primer: 4200 rev and Cap3500 for. Expected fragment size: 885 bp. <br/>
+
-
PCR was performed following the standard protocol. <br/>
+
-
[[Image:Freiburg10 1110 testdigestionhanna1label.png|thumb|none|800px]]

Expected results for the 1% agarose gel:
 +
*P666: about 2100 and 750 bp
 +
*P729: about 3300 and 20 bp

... 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>
 +
 
 +
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.

These purified and concentrated viral particles could be used for biophysical measurements, there for the possibility to detect the viral particles by absorption was interesting for us.

For the first Western Blot try, we investigate whether is is enough to concentrate the virus stock (from cell supernatant) and then to simply load it onto a SDS-PAGE gel and perfom immuno-staining. <br/>
+
-
For this purpose 8 mL virus stock were concentrated via amicon filtration. <br/>
+
-
* First, amicon filter was washed with 4 mL PBS.
+
-
* Then 4 mL virus stock was loaded onto the filter and centrifuged at 3000 rpm for 15 minutes.
+
-
* Flow-through was discarded and additional virus stock was loaded, centrifuged at 3000 rpm for 25 minutes.
+
-
* Flow-through was discarded, remaining solution was re-suspended and additional virus stock was added. Amicon filter was centrifuged at 3000 rpm for 50 minutes.
+
-
* Flow-through was discarded. Residual protein solution: 500 µL. Filter was washed with 3 mL PBS, centrifuging 35 minutes. 
+
-
* 2 x 20 µL protein solution was taken and mixed with Laemmli buffer and stored over night @ 4°C.

* 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.

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/>
 +
Gel was put into Coomassie dye, heated for 30 seconds in microwave and incubated for 1 hours shaking. <br/>
 +
Gel was decolorized in acetic acid (20%). <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.

SDS PAGE and Coomassie staining

Investigator: Hanna

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

  • 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%).
