Transfer of MITF to pSB1C3
Transformation results
From 24/8 Due to late transformation 24/8, colonies didn't turn red until very late in the afternoon, revealing only two white colonies. These will be picked for colony PCR tomorrow.
Construction of His⋅SOD fusions
Plasmid prep
From 24/8 ON cultures
- E.Z.N.A. Plasmid Mini Prep kit
- Elution volume: 50 μl
- Samples eluted twice to increase plasmid yield

Transfer of RFP cassette into pEX
Transformation results
From 24/8
Good colony yield but no red. Recalled that the RFP cassette is expressed from a LacI-sensitive promoter; since pEX expresses the LacI repressor, IPTG has to be added to induce expression of the RFP cassette.
Transformation
Plated an Amp 100 plate with 50 μl 0.1 M IPTG. LB agar was then plated with quick-transformed cells, transformed with the 24/8 ligation mix.
- 1.5 μl ligation mix
Johan
- Ligate cut bFGF into cut C-vector
1 µl vector
5 µl bFGF
2 µl 10x buffer
1 µl T4 ligase
11 µl H2O
20 min 22 °C
Then heat-inactivation
- Transformation of bFGF+C
