Andreas

Transfer of pEX.nCPP⋅SOD⋅His to BL21

Gel verification

Re-run of 2/10 BL21 samples

1. BL21 pEX.nLMWP⋅SOD⋅His: A & B
2. BL21 pEX.nTra10⋅SOD⋅His: A & B

1 % agarose, 120 V

Expected bands:

1. 744 bp
2. 765 bp

Results

1. Both clones verified
2. Clone A verified; weak band for clone B

ON cultures

• 3 ml LB, 30 °C
  1. A: BL21 pEX.nLMWP⋅SOD⋅His
  2. A: BL21 pEX.nTra10⋅SOD⋅His

Transfer of nCPP⋅SOD⋅His.RBS.yCCS operon to pEX

Colony PCR

Picked 2 new colonies of each of the two constructs transformed 30/8:

• 5. pEX.nTra10⋅SOD⋅His.RBS.yCCS 1: A & B
• 6. pEX.nTra10⋅SOD⋅His.RBS.yCCS 2: A & B

Standard colony PCR settings

• Elongation time: 2:00

Gel verification

0.8 % agarose, 100 V

Expected bands:

• 5. 1553 bp
• 6. 1553 bp

Results

• 5. Relevant band for clone B; too large insert (double?) for clone A.
• 6. Relevant band for clone B; too large insert (double?) for clone A.

ON cultures

• 5 ml LB, 37 °C, 250 rpm
  • pEX.nTAT⋅SOD⋅His.RBS.yCCS 2: A & B
  • pEX.nTAT⋅SOD⋅His.RBS.yCCS 3: A & B
  • pEX.nTra10⋅SOD⋅His.RBS.yCCS 1: A & B
  • pEX.nTra10⋅SOD⋅His.RBS.yCCS 2: A & B
  • pEX.nLMWP⋅SOD⋅His.RBS.yCCS 2: A & B
  • pEX.nLMWP⋅SOD⋅His.RBS.yCCS 3: A & B

Verification of pSB1x3 plasmids

Due to some strange growth results with our stock plasmids (pSB1x3.BBa_J04450), I decided to verify their antibiotic resistance. Restreaked clones of the following plasmids (w/ BBa_J04450 inserts) onto Amp 100, Km 50 and Cm 25 plates:

• pSB1A3
• pSB1C3
• pSB1K3
• pSB1AC3
• pSB1AK3
