Results for Starch plates

- Add 5mL of iodine

- 1A1 or IA751 : big zones of clearance

- IA751 + ECE112 : no zones of clearance (photos), just small white points on colonies : the gene AmyE seems to be knocked out, transformation ok!

- 1A1 + ECE112 : problem, soft agar melted... impossible to observe!


Transformation

- We used IA751 plate from 12/08/08, vectors ECE 153, 166, 171

- Spectrophotometer : blank made with medium A

Time (min) 0 20 40 60 80 100 120
OD650 0.1487 0.1541 0.1642 0.1980 0.2470 0.3205 0.3643

- t0 = 120min

- Follow the protocol of transformation

- Plasmid miniprep of ECE153, 166, 171 (to make the transformation)

- Nanodrop ( to add 0.5μg of DNA for transformation)

Vetor 260/280 μg/mL quantity of DNA to add for transformation (μL)
ECE153 1.5 18.4 27.2
ECE166 1.83 39.5 12.7
ECE171 1.83 115.8 4.4

- Plate (with appropriate antibiotics)

  • ECE166 : Cm5
  • ECE153 : Spc50
  • ECE171 : Kan5 (to prepare agar plate, 40μL of Kan 25mg/mL into 200mL of agar)

Check our stock of ECE171

- We made big stocks of ECE171, before keeping it, we wanted to check it, so we run double digest on a gel!!

- Results : problem!!

- 2 possible causes : Double digest was made " days before and kept in the freezer (possible degradation) + too much DNA on the gel

- New double digest (from pellets in the freezer) + new gel

- Results : ok!
