Minipreps were conducted with PeqGOLD MiniPrep Kit (Peqlab) according to the user manual.
+
In order to gain further plasmid material of the new vector pSB1C3 was transformed into <i>E. coli</i>(DH10B) as described in the protocol. <br>

<li>Observations & Results: <br>
-
The retransformation was successful since all plates showed numeours colonoes except the negative control.
+
The transformation was not successful. No colonies could be observed at the plates. Since this vector has a canamycin resistance instead of ampicillin as the usually used pUC18 we suggest that the antibiotics concentration in the agar was simply to high.</li>
