=== Digestion of flhD/C PCR product with EcoRI and SpeI ===

''Methods:''  Restriction digest and gel electrophoresis <br><br>
 +

''Experiment done by:'' Maria<br><br>

''Notes:''<br>
 +
To verify if a ligation has occurred Taq PCR product of coloni 4 and 9 (see [https://2010.igem.org/Team:SDU-Denmark/labnotes2#Coloni_PCR_of_flhD.2FC_in_pSB1C3 Coloni PCR]) was digested with the same restiction enzymes used for the digestion of flhD/C DNA and pSB1C3 prior to ligation.<br> If an ligation has occurred, then the restriction sites of EcoRI and SpeI should be intact, and two fragments of 122bp and 170bp should be observed on the gel, indicating VF2-E site and S site-VR respectively.<br>
 +
RFP (PCR poduct of coloni no.8) was used as controle.<br>
 +
2.5uL of undigested PCR product of coloni 4, 8 and 9 were loaded onto the gel as well.<br>
 +
Samples were loaded onto a 2% agarose gel. Hyper Ladder II was used as marker.<br>

 +
''Analysis:''<br>
 +
The 2 bands at app. 100bp and 200bp respectively indicates that the E and S restiction sites have been preserved, suggesting that a ligation has occured.<br>
 +
An ON culture of coloni 4 and 9 is made to use for mini-prep.<br>
