Preparation of Top10 chemically competent cells

No growth on neither Amp 100, Cm 25 nor Km 50 plates - no contamination of competent cells.

pSB1C3.N-TAT & .N-Tra10

Successful transformation. One colony of each plate picked and dissolved in 10 μl and saved in fridge for later glycerol stock preparation.

Assembly of new parts

Planned and designed cloning strategies for some of the assemblies I will be constructing:

pEX.SOD
N-TAT⋅SOD⋅His
N-Tra10⋅SOD⋅His
N-LMWP⋅SOD⋅His (N-LMWP n/a)
His⋅SOD⋅C-Tra10 (C-Tra10 n/a)
His⋅SOD⋅C-TAT (C-TAT n/a)
His⋅SOD⋅C-LMWP (C-LMWP n/a)
RBS.yCCS

Digestions

[pSB1C3.SOD] = 105.5 ng/μl

[pMA.SOD⋅His] = 246 ng/μl
[pSB1C3.N-TAT] = 200 ng/μl
[pSB1C3.N-Tra10] = 151 ng/μl
[pSB1K3.RFP] = 104 ng/μl
