The inserts for TEV semm to be right in the most cases, but the backbone has mutated and it should be cloned into a new pSB1C3 with new same restriction enzymes (XbaI+AgeI)!

The forward sequencing of CaMV p35S is right but the analytical digestion is wrong. Maybe further parts are downstream of the promoter?! Reverse sequencing should be performed for further analysis.

Aim of the experiment: Picking of of E. coli XL1 blue transformed with F42+F38 (t35S), F17+F40 (Pif 3) and F41+F39 (npt).

Procedure:

The picked colonies were transferred into cell-culture tubes with air-permeable, sterile cover containing 5 mL of LB-medium + 5 µL chloramphenicol(1000x).
