Check promoters

On Friday, PCR out promoters, we want to check them.

- Run a gel

- Results : good size of bands!!!

Test Ery efficiency

Since all Ery plates grew, we want to check the antibiotic stock.

- New Ery plate of IA751 (they should die)

- New LB stock (Ery5) with IA751

Single colony plates

- New plates (Cm5 + Amp100) with single colony of ECE188 (from 14/08), ECE189 (from 13/08) and ECE190 (from 14/08)

- Grow the same single colony into LB with antibiotic

Transformation of glycerol stocks of B.S.

The result from the last transformation of glycerol stocks was negative> We tried again with two different protocols.

  • First protocol

- Spin the glycerol stock, throw out the supernatant (just keep about 100μL), add 0.5μL of Medium B

- Incubate about 1h15

- Add 0.6μg of ECE166 (because we managed to transform BS with this vector)

- Incubate 1h30

- Plate on Cm5 plates (DNA less control and transformed cells)

  • Second protocol

- Spin the glycerol stock, throw out the supernatant (just keep about 100μL), add 0.5μL of Medium B

- Add 0.6μg of ECE166 (because we managed to transform BS with this vector)

- Incubate 30min

- Plate on Cm5 plates (transformed cells)


- Plate cells after 10min of incubation (without DNA) on blank plates (to see if they are alive)



Transformation of AgrA and AgrC

AgrA and C gell-extracted ligation was transformed into Top 10 cells using standard protocol. Puc9 was used as a positive control.
