Transformation in Trp K.O.
The 3 newly competent strains (JW4356-2, JRG 1046, JRG 465) will be transformed with :

- RO2#4 + BB1 (+Amp, Kana) -> double transformation.

- RO2#4 (+Kana)

- RO1#1 (+Kana)

- RO1#1 + BB1 (+Amp, Kana) -> double transformation.

Note : the 3 control (1 ug/ul DNA, 100 pg/ul DNA, 10 pg/ul DNA -> 10ul for each transf) + KANA. We will count the nb of clones the next morning on the plates to determine transformation efficiency.

The normal protocol for these transformation has been used (50 ul cells + 10 ul total volume DNA) : 20 min on ice, heat shoch (45 s at 42°C), SOB (500ul) at 37°C for 1 h, plated on according antibiotic LB/Agar plates. Put overnight at 37°C.

Note : the double transformation : the whole tue (about 560 ul) is added to the plates. The single transformation : only 150 ul of the mixture.
