* DNA synthesis (JeT, cFos, Min)
 
-
* Purification of cDNA via 2% / 3% agarosegel
 
-
=> Only bands at ca. 50 Bp => no successful amplification

Lab: LV, SH
 
-
* No transformations could be observed
 
-
* Replace Phsuion stocks to Phusion Master Mix from Nathan
 
-
* Repeat DNA synthesis with a different protocol: 1:10 - 1:1000 dilution of Oligos, 95° 5',  7* [95° 45'' 58° 45'' 72° 1'], add 1:10 diluted primers, 95° 5' 25* same temperatures
 
-
* Annealing successful for JeT and Min
 
-
Annealing might not have been successful with Fos beacuse it contains a very repetetive proximal promoter.

-
* gel purfifcation of JeT and Min
 
-
* Repeat PCR of pcDNA5/FRT and mcherry with lower annealing temperature (58°C) and fresh Polymerase: Follow PCR protcol from Strategene site directed mutagenesis kit.
 
-
mcherry PCR might not have been successful because we used a template we didn't make ourselves - does it contain TE?
 
-
* PCR worked for pcDNA5FRT but not for mcherry
 
-
* DpnI digest of pcDNA5FRT 1,3,4,6

-
* DNA synthesis for Fos (proximal) and Fos (core)
 
-
* Transformation of DH5a with pcDNA/FRT ΔPstI
 
-
Gave many 1000 colonies. Probably a contamination (?), whci hwould explain why there was no mutagenesis (see below)
 
-
* HeLa cells, MCS7 and U20S were splitted 1:3. Therefore DEMED medium (containing additionally 10% FCS, Pen-Strep, glutamate and non-essential aminoacids) was removed. Cells were washed afterwards with HBSS and trypsinised with 1 ml of trypsin and incubated for 5 min. at 37°C 5% CO2. The used flasks were filled up to a final volume of 7 ml with DMEM. 2 ml of the suspension was transfered to a new flask, 5 ml DMEM was added and incubated for another 3-4 days at 37°C and 5% CO2.
