Start date: 22/07    End date: 22/07<br>
 +
''Methods:''  Coloni PCR and gel electrophoresis <br><br>
 +
''Protocol:''[https://2010.igem.org/Team:SDU-Denmark/protocols#CP1.3 CP1.3] <br><br>

''Notes:''<br>
 +
Coloni PCR was made on flhD/C in pSB1C3 from [https://2010.igem.org/Team:SDU-Denmark/labnotes2#Transformation_of_flhD.2FC_in_pSB1C3_and_test_plasmid_in_Top_10_E.Coli Transformation].<br>
 +
All remaining white colonies from plates plated with cells transformed with L2 and L3 ligation mixtures (see [https://2010.igem.org/Team:SDU-Denmark/labnotes2#Ligation_of_flhD.2FC_.28native_coding_sequence.29_and_pSB1C3 Ligation]) was selected.<br>
 +
coloni 1-6 is taken from L2.3 plates<br>
 +
coloni 7-15 is taken from L3.2 plates <br>
 +
coloni 16-27 is taken from L3.3 plates<br>
 +
coloni 28 is taken from streak plate of PCR no. 4
 +
coloni 29 is taken from streak plate of PCR no. 9 (see [https://2010.igem.org/Team:SDU-Denmark/labnotes2#Coloni_PCR_of_flhD.2FC_in_pSB1C3_2 Coloni PCR])<br>

 +
 
 +
''Analysis:''<br>
 +
None of the samples contained amplified DNA.<br>
 +
This indicates either that the flhD/C gene has not been inserted to the pSB1C3 backbone or an insertion has been made but the flhD/C primer has not been able to anneal to the template.<br>
 +
To verify that a ligation has occurred, PCR product 4 and 9 from [https://2010.igem.org/Team:SDU-Denmark/labnotes2#Coloni_PCR_of_flhD.2FC_in_pSB1C3 Coloni PCR] was digested with EcoRI and SpeI.<br>
