Transformation of DH5α|pPS16_004 and DH5α|pPS16_007

By Caroline and Mathilde

The 04/06/2016 transformations show white colony growth for gBlocks 4.2 clone 3 and GFP1-9 (clone 1), but blue colonies only for 4.1 clone 3.

Thus this last gBlock 4.1 clone 3 was transformed again following the same protocol as the 21/06/2016 with : 50μg of competent DH5α cells 4.1 ligation product in 5μL of the plasmid puc19 4.1 clone 6 extracted DNA (which presented a good size strip on electrophoresis)

6 clones of each of the other transformations pPS16_001, pPS16_002, pPS16_003, pPS16_005 and pPS16_006 were placed in 4mL of LB added to Ampicillin (50µg/mL) at 37°C, 180RPM. For 2.2 just 2 clones were cultivated because there was not more colony. To obtain more colonies, another transformation (Heat shock competent cells, section protocols) was made with 50µL of cells, 5µL of plasmid. 50µL of transformed bacteria were displayed on LB + Ampicillin (50µg/mL)dishes.
