Colony PCR of “3812-02” “3813-02” “01-3902” “01-1302” starters launched on positive results

No colony for “43” “44” “47” “013002”

Preparation of the backbone pSB1C3

Transformation of “013002” “41” “44” “47” into C2987

Plasmid purification of “45” “01-36” “381302” “38” “01-1202” “3812-02” “3813-02”

Colony PCR of “47” “01-3002” “43” “44” => almost everything is positive!!! Great day!

Plasmid purification (miniprep) of “44” “47” “43” “38” “01-1302” “01-1202” “01-3002” “45”

“01-1302” “01-36” “3813-02” seems good so they are send for sequencing.

Construction : Digestion E/S of “38” “01-36” “01-35” “01” and Digestion X/P of “44” “47” “43” “48” “44” “45” “1302” “3813-02” “39-02” “40” “3812-02”

Starter launched on “01-1202” “01-3002” for production and on “0136” for miniprep

Ligation in pSB1C3 of “0136-02” “01-381302” “01-381202” “01-3902” “01-1302” “38-3902” “0136-40” “0136-45” “0136-48” “0135-43” “0135-44” “0135-47”

Transformation of “01-3002” in BL21, of pSB4K5 and pSB3T5 in TG1 and transformation of ligation product in TG1

Purification of “01-1202” (1) and (2):

Induction by IPTG

Storing the cells at -80°C

Colony PCR of “013002” “013002” => all results are positive

Production of “01-1202” : Sonication of cells, centrifugation 10 min at 4500 rpm, ultracentrifugation 45 min at 4500 rpm, solubilizing membrane in Triton 1% during 2h and incubation overnight.

Preparation of SDS Page 15% and a western blot with products of yesterday => results are not good so we have to resart the production

Culture of “01-1202” and “01-3002” in anaerobic condition, cells were centrifuged 10 min at 4500 rpm and pellet were stored at -20°C

A western blot was done → Production of Cytochrome, monomer in the membrane and dimer in the cytoplasm

The next step is to purify “01-1202” and “01-3002” and start a culture on 01-3502 in anaerobic condition
