Assembly of new parts

Gel verification of part digestions

Ran gels of digestion samples in parallel with undigested samples to verify successful digestions and insert sizes.

Gel 1

Gel verification of digested samples, gel 1.
&4 μl λ; 3 μl sample.
λ = O'GeneRuler 1 kb DNA ladder.

1 % agarose, 110 V

Gel 2

Gel verification of digested samples, gel 2.
&4 μl λ; 3 μl sample.
λ = O'GeneRuler 1 kb DNA ladder.

1 % agarose, 110 V

Results
Successful digestion with corresponding bands for all digested samples. N-TAT and N-Tra10 not verified, since gel was run too far, but plasmid linearization should indicate successful digestion.

Most samples show somewhat incomplete digestion. For digestions with FastDigest enzymes, this may be an indication of old/inactive enzymes. Especially PstI should be analyzed for activity.

Colony PCR

Picked new colonies for colony PCR from 14/9 plates:

• pSB1K3.N-TAT⋅SOD⋅His: TAT⋅SH 1-5
• pSB1K3.N-Tra10⋅SOD⋅His: Tra10⋅SH 1-5
• pEX.SOD 1-4

Standard colony PCR settings.

• Elongation: 1:30

Gel verification

Colony PCR gel verification of N-TAT⋅SOD⋅His clones.
4 μl λ; 5 μl sample.
1 kb λ = O'GeneRuler 1 kb DNA ladder; 50 bp λ = GeneRuler 50 bp DNA ladder.

Colony PCR gel verification of N-Tra10⋅SOD⋅His clones.
4 μl λ; 5 μl sample.
λ = O'GeneRuler 1 kb DNA ladder.

Colony PCR gel verification of pEX.SOD clones.
4 μl λ; 5 μl sample.
λ = O'GeneRuler 1 kb DNA ladder.
