Main purpose

Run gel with 9 PCR samples of Nir operon from Pseudomonas aeruginosa

Transformation of Biobricks

PCR reaction for Nir operon

Who was in the lab

Ariadni,Henrike,Julia,Natalia

Procedure

Run gel

  • 3 samples from PCR on the 09.07.2013 using PAO1 as template source
  • 3 samples from PCR on the 09.07.2013 using PCR purification of 08.07.2013 as template source
  • ladder broad range biggest fragment = 20 kb
  • 3 samples from purification of 09.07.2013

Transformation of Biobricks

According to the iGEM protocol ([http://parts.igem.org/Help:Protocols/Transformation transformation protocol]) with slight changes.

  • step 1: 100 μl cells
  • step 2: 1.5 μl of the resuspended DNA
  • step 6: 90 sec (instead of 60 s)at 42 oC
  • step 9: Incubation without shaking

Comments

Kanamycin plates were of bad quality

Tetracyclin plates were made by adding 22.5 uL of tetracyclin stock to LB plates

  • Stock tetracyclin: 10 mg/mL
  • Final concentration in plates: 15 ug/mL

Conclusions

Nir forms a nice, but weak, band in most samples but the fragments are still far longer than expected. It looks like they are somewhere around 16 kb where we rather expected 9102 bp. We will try to cut down the extension time and see if we can get something out of it.
