C. albicans & C. glabrata

- Test of supercompetent E.coli cells with the transformation efficiency kit (from iGEM)
    ⇒ Did not work! No colonies

- Got cDNA of Candida albicans and Candida glabrata from Oliver Baders Lab:
       Candida albicans strain SCS314
       Candida glabrata strain CBS138
    ⇒ Both high concentrations : dilution (10 µl DNA + 990 µl H2O)

A. fumigatus & A. nidulans

- Preparation of competent cells E.coli DB3.1 (mutated gyrase, resistant against ccdB) with CaCl2 (see Protocol for fresh comp. cells)
- Transformation with pDONR207 and pDEST (Plating of 50µl and rest on LB+ Cm plates, incubation over night at 37°C)
       ⇒ Trafo worked! Single colonies in 4 ml LB + 4µl Cm
       ⇒ Also saving of the strains on plates
- Plasmid isolation with M&N Kit, Elution in 70µl dH2O
- Nano Drop:
