SH:
- Miniprep of GFP template plasmid, pcDNA5/FRT
| Nr | pcDNA5/FRT | GFP |
|---|---|---|
| 1 | 4,7 | 39,7 |
| 2 | 5,9 | 14,9 |
| 3 | 3,7 | 3,8 |
| 4 | 5,0 | 7,8 |
- Maxiprep pcDNA/FRT 188.7ng/µL
LV:
- Extraction of CMV promoter from 2008 distribution
- Transformation of DH5a cell with CMV promoter
- portzughtr

Lab: LV, SH, CZ
- Annealing of Oligos (JeT, cFos, Min)
- Purification of cDNA via 2% / 3% agarosegel
=> Only bands at ca. 50 Bp => no successful amplification
- Site directed mutagenesis of pcDNA5/FRT and mcherry
- Dpn1 digestion
- Transformation of DH5a

Lab: LV, SH
- No transformations could be observed
- Replace Phsuion stocks to Phusion Master Mix from Nathan
- Repeat Annealing of Oligos 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
