Reception of the four DNA constructions: CsgA Wild type, CsgA PolyHis1, CsgA PolyHis2, CsgA Modular

NM522 and DH5α cells (in liquid LB medium) were cultured overnight under agitation at 37°C for later transformation.

Transformation of NM522 and DH5α strains with each one of the following plasmids.
Selection of transformed bacteria on antibiotic plates depending on the plasmid.
26/06
Transformation analysis: all the transformations were successful except the ones with plasmids pHC03, pHC06, pHC07 and pHC09. Transformation of these four plasmids was repeated with a new protocol.
Clones of transformed strains containing pHC01, 02, 04, 05 and 08 were cultured in 5 mL LB medium containing 50 µL of the specific antibiotic at 37°C and appropriate plates were streaked with isolated colonies likely to contain transformed bacteria.
27/06
Transformation analysis: all the transformations were successful and plates containing pHC06 plasmids showed pink bacteria, as the rfp in the plasmid is expressed in presence of a strong promoter (like J23100).
A protocol for nickel titration was searched and nickel was stored for later experiments.
