Seemingly correct bands for samples 1, 3, 4, 5 and 8. More unsure results for 6 and 7, while 2 seems to contain more than one insert, or has been digested at several places.

Gel verification

Gel verification of sample digestions.
4 μl λ; 3 μl sample.
1 kb λ = O'GeneRuler 1 kb DNA ladder. 50 bp λ = GeneRuler 50 bp DNA ladder.

Due to the risk of pSB1A2.RBS.yCCS and pEX.N-TAT⋅SOD⋅His having previously been mixed up, a gel was run on the digested samples (after 15 min incubation) to verify the excised insert size. Remaining samples were also run on the gel to verify digestion.

1 % agarose, 120 V

Expected bands

  1. pSB1A2.RBS.yCCS X+P: 806 bp, 2061 bp
  2. pEX.N-TAT⋅SOD⋅His X+P: 558 bp, 4453 bp
  3. pSB1K3.N-TAT⋅SOD⋅His S+P: ≈2730 bp
  4. pSB1K3.N-Tra10⋅SOD⋅His X+P: 588 bp, 2188 bp
  5. pSB1K3.N-Tra10⋅SOD⋅His S+P: ≈2760 bp
  6. pSB1C3.N-LMWP⋅SOD⋅His X+P: 567 bp, 2054 bp
  7. pSB1C3.N-LMWP⋅SOD⋅His S+P: ≈2610 bp
  8. pEX.RFP X+P: 1095 bp, 4453 bp

Results
Seemingly correct bands for samples 1, 3, 4, 5 and 8. More unsure results for 6 and 7, while 2 seems to contain more than one insert, or has been digested at several places.
