Andreas

Assembly and cloning

Gel verification

Re-run of 27/9 colony PCRs.

Gel 1
1 % agarose, 110 V

Gel 2
0.8 % agarose, 90 V

Expected bands

1. pEX.N-LMWP⋅SOD⋅His (K): 744 bp
2. pEX.N-TAT⋅SOD⋅His: 735 bp
3. pEX.N-Tra10⋅SOD⋅His: 765 bp
4. pEX.N-LMWP⋅SOD⋅His (C): 744 bp
5. pSB1K3.N-LMWP⋅SOD⋅His.RBS.yCCS: 1645 bp
6. pSB1K3.N-TAT⋅SOD⋅His.RBS.yCCS: 1636 bp
7. pSB1K3.N-Tra10⋅SOD⋅His.RBS.yCCS: 1666 bp
8. pSB1C3.N-LMWP⋅SOD⋅His.RBS.yCCS: 1645 bp
9. BL21 pEX.N-TAT⋅SOD⋅His 3: 735 bp
10. BL21 pEX.N-TAT⋅SOD⋅His 4: 735 bp

Results
Listing clones of seemingly correct sizes, thereby potentially correct constructs:

1. 1
2. 1 & 2
3. 1 & 2
4. No correct clones
5. 2, 3 & 4
6. 1, 2 & 3
7. 1, 2, 3 & 4
8. No correct clones
9. 1 & 2
10. No correct clones

For further verification constructs should be sent for sequencing. However, we will await the sequencing results from samples sent 27/9, as they were also used for building these new assemblies.

ON cultures

Set ON cultures for plasmid prep (constructs 1-8) and glycerol stock (9)

• 5 ml LB + appr. antibiotic (Amp 100 or Km 50); 37 °C, 220 rpm

Over expression

• Start up cultures

DNA

pEX.SOD

pEX.yCCS

pEX.SOD.his

pEX.his.SOD
