  • Preparation of TB media with an Agar concentration of 0.4 %, 0.2 % and 0.1 %.

First microscope test using MG1655 in 6 small chambers from Labtek:

3 types each type twice:

  • In I and II each chamber was filled with just 100 µl LB agar to cover the whole ground.

Notes: Because of surface tensions the solutions tend to be thicker at the borders of the chamber than in the center.

Tuesday 02/09/2008

First approach in microscope seems to be good and can be followed up.


Yesterday overnight cultures of E.Coli HCB33 and E.Coli MG1655 have been inoculated in 3 ml LB media. Today they were diluted with additional 4 ml LB and splitted into two 3 ml falcon-samples.
Followed by incubation at 37 °C.

Glycerol-stocks

  • The other 1 ml of each sample was used to create a glycerol stock.
    • 1 ml of the ONC mixed with 150 µl of 80% glycerol by vortexing. Storage at -80 °C after 30 minutes of rest.



First test producing fluorescent strains HCB33 and MG1655 strains.

  • Therefore our strains will be transformed with
    • 11tg a plasmid with Amp-resistance which should allow the expression of GFP.
    • BBa_I7100 from the registry, this should be expressing GFP, the production may be repressed with TetR. Kan-resistance.

Altogether there were 4 transformations.
BBa_I7100 and 11tg each with HCB33 and MG1655.

The Transfomations was prepared using the following protocol:

Transformation

  • 1. -80 °C cultures thawing on ice.
  • 2. The spot has been cut from the registry folder and was transfered it to a 1,5 ml tube.
  • 3. 10 µl of prewarmed EB-Buffer have been put on the spot. Then tube was incubated at 37 °C for 20 minutes.
  • 4. 2-4 µl of plasmid DNA were given to 50 µl of competent cells and incubated for 20 minutes on ice.
  • 5. Afterwards the cells were heat shocked for about 45 seconds at 42 °C.
  • 6. Then each tube was put back into ice for 2 minutes.
  • 7. 400 µl of prewarmed LB has been added to each tube.
  • 8. Then the cells were incubated for 1 hour at 37 °C and 300 rpm.
  • 9. 150 µl and 300 µl of each tube were distributed on separate agar-plates containing the right antibiotics.
    • cells with 11tg on Amp plates
    • cells with BBa_I7100 on Kan_plates
  • 10. Plates were incubated overnight at 37 °C



Furthermore TB media, which contains 2% agar was produced and prepared for the4 autoclave.

The agar stocks prepared on monday were aliquotted on 1,5 ml eppi tubes. 1 ml per eppi.

Preparation of m9 media containing agar 2, 0.4, 0.2 and 0.1 % agar.

Not successful with BBa_I7100 and MG1655.
