-
* One more try to get Fiu protein on pSB1A3 backbone. NovaBlue transformed with ligation products of pSB1A3 and Fiu.
 
-
 
-
* Grew colonies for FhuA and OsmE midi preps.
 
-
 
-
* Carried out midi preps for FhuA and OsmE ( [FhuA]=378.9 ng/ul, [OsmE]=113.2 ng/ul).
 
-
 
-
* Transformed Nova Blue with biobrick part BBa_B0014 (double terminator)
 
-
 
-
* Culture colonies of BBa_B0014 transformants to get ready for mini prep.
 
-
 
-
* PCR FhuA and GFP for assembling together a quick and dirty fusion to be ready prior to BioScaffold arrival.
 
-
 
-
* Carried out colony growth (agar & liquid) for the AraC promoter (2 parts BBa_R0080 (lacking O2 region) and BBa_R0081 (the O2 region).
 
-
 
-
* Miniprepped DNA from cultures of BBa_R0080 and R0081.
 
-
 
-
* Attempted a 2-way ligation and of the BBa_R0080 and R0081 parts. The final product should be a 2-component biobrick on a plasmid in 5'-R0081-R0080-3' direction which can be transformed into cells.
 
-
 
-
 
-
* R0081 part was purified by gel extraction after being treated by double digest. R0080 and R0081 were ligated together and used to transform NovaBlue cells.
 
-
 
-
* First attempt to make the AraC promoter from the two parts failed.
 
-
 
-
* Fiu still not being ligated on ANY backbone.

Lanes 7-9 illustrate Double Digest with XbaI and SpeI,Single Digest with XbaI and Uncut versions of the plasmid carrying R0080. Similarly lanes 10-12 show the same for R0081. The promoter fragments are 149bp and 183bp respectively and do not appear on the gel but the presence is
