DNA-Origamis normann
DNA-Origamis with Alexa/noNIP, NIP/Alexa, NIP, noNIP were made. The protocol of july 24th was used.

Preparation of 293T transfection normann

In order to transfect the 293T-cells with CMV+YFP tomorrow, the amount of cells per ml was determined with the "Neubauer cell chamber" --> 2,62*10E6 cells/ml
To transfect cells with 1µg DNA in a 6-well plate, you need ~6*10E4 cells per well, so 20µl of the suspension was given in each well and 2ml DMEM was added.

Digestion of CFP normann
In order to put the gene for CFP behind the CMV-promotor on our transfectionvector to make a double trasnsfektion with YFP, the plasmit carrying CFP was digested using pst1 and Xba1.
The digested gene was brought on an agarosegel and the expected band was cut out, after the followed the extraction out of the gel using the "QIAquick gel extraction kit"

preparation of ss Phage DNA normann
Because the ss PhageDNA ,which is needed for the origamis, is nearly empty phages were harvested out of a overnight culture.
Harvesting happened like it is descriped under Methods.
Preparation of the ssDNA was done following the QIAPrep Spin M13 Kits protocol.

fluorescence microscopy (Normann and Kathrin)
To test if the CMV-promotor in the transfectionvector allows a succesful transfection of a protein TV_CMV_5_YFP clone D was transfected to 293T cells and analysed by fluorescence microscopy.

Figure_fluorescence microscopy from left to right: 293T cells transfected with the Transfectionvektor+CMV-promotor and a YFP construct/ control/ brightfield picture of the control
As expected the transfectionvector with CMV promotor induces expression of the yellow fluorescent protein.

Analysis of the split beta Lactamase was performed by LiveBLAzer (invitrogen). After loading the cells with CCF4-AM the molecule is converted into CCF4 by an esterase in the cell. Beta Lactamase splits the FRET-pair CCF4 (absoption 409, emission 520nm) into two fragments. One of the fragments can still be stimulated by 409nm to detect an emission at 447nm)
