Removal of insertion in BioBrick suffixes

Plasmid prep

From 8/10 stored pellet

  • 50 μl elution buffer.
DNA concentration
Sample Conc [ng/μl] A260/A280
pSB1C3.SOD 163.1 1.94

Digestion

  pSB1C3.
SOD
10X FastDigest buffer 2
DNA (1 μg) 12.3
dH2O 3.7
FD EcoRI 1
FD SpeI 1
  20 μl
  • Incubation: 37 °C, 30 min

Gel verification

Gel verification of pSB1C3.SOD digested with EcoRI and SpeI.
3 μl λ; 3 μl sample.
λ = O'GeneRuler 1 kb DNA ladder

1 % agarose, 140 V

Expected bands

  • Vector: 2175 bp
  • Insert: 495 bp

Results
Band slightly larger than expected, but this may also be due to bound restriction enzymes and/or other disturbances. Proceeded to gel extraction.

Gel extraction

Digested pSB1C3.SOD separated on 1 % agarose gel at 110 V, 17 μl sample volume. SOD band extracted and DNA, as well as DNA from samples stored in -20 °C 7/10, were purified using the E.Z.N.A. Gel Extraction kit.

DNA measurements extremely low, but proceeded to ligation/cloning anyway.
