Coomassie gel on IPTG treated IgG protease
I removed the coomassie solution from both the IgG protease gel and also the bFGF gel. Then I poured a couple of mls of destaining solution onto the gels and left ON.

Transformation results
Colonies on all four plates, however only one colony on three of them. These were also not discovered until after colony PCR was prepared. Interestingly, the plate with many colonies was the only construct carried on the pSB1A3 vector:
- pSB1C3.N-LMWP 1:10 = 1 colony
- pSB1C3.N-LMWP 1:100 = 1 colony
- pSB1C3.C-LMWP 1:10 = 1 colony
- pSB1A3.C-LMWP 1:100 = many colonies
Colony PCR
6 clones (A, B, C, D, E, F) were picked from the "pSB1A3.C-LMWP 1:100" plate for colony PCR:
Colony PCR (illustra ready-to-go PCR beads)
- 22.5 μl dH2O
- 1.0 μl VF2
- 1.0 μl VR
- 0.5 μl cell suspension
Positive control: pSB1A3.BBa_J04450 purified plasmid.
Amplification
- 95 °C - 10:00
- 95 °C - 0:30
- 55 °C - 0:30
- 72 °C - 1:00
- Cycle back to step 2 29 times.
- 72 °C - 10:00
Gel verification
1 % agarose, 90 V, 60 min
Loaded volume:
- GeneRuler 50 bp DNA ladder: 2 μl
- Samples: 4 μl
Results From what the results show, I chose the wrong ladder. Still, bands are unreasonably large (1500 bp ?). Interesting band at ≈300 bp in sample A. Since the pSB1A3 vector itself gives about 270 bp from the colony PCR, the band is probably too small to carry anything of interest.
Plasmid prep
Continued from 30/7
From ON cultures yCCS A & B, MITF A-D, MITF RED A & B.
Sample | Conc [ng/μl] | A260/A280 |
pSB1C3.yCCS A | 94.77 | 1.86 |
pSB1C3.yCCS B | 85.78 | 1.93 |
DNA conc. not measured for MITF samples, as these will only be used for PCR.
Glycerol stocks
Continued from 30/7
From ON cultures of yCCS A & B.
Old non-mutagenized glycerol stocks of yCCS were discarded.
