=Amplification of the circular plasmid pSB1C3 for the Subtilin immunity BioBrick=
+
=Glycerol stocks=
-
 
+
Today we made [[Team:Newcastle/Glycerol_stocks|glycerol stocks]] of our filamentous ''Bacillus subtilis'' 168 strain.
-
==Aim==
+
-
The aim of this experiment is to amplify the plasmid pSB1C3 for the construction of the [[Team:Newcastle/End of crack & signalling system|subtilin immunity BioBrick]] with the help of two Phusion PCR reactions using old and new primers, and to perform gel electrophoresis to check whether amplification was successful.
+
-
 
+
-
==Materials and Protocol==
+
-
Please refer to  [[Team:Newcastle/PCR| PCR]] for Phusion PCR protocol and [[Team:Newcastle/Gel_electrophoresis|gel electrophoresis]]. The details for the PCR reactions are given below.

'''Table 1''': Table represents two Phusion PCR reactions amplifying the plasmid pSB1C3 so that it can be ligated together with other Subtilin Immunity fragments using the Gibson Cloning method.
+
-
* The extension rate of the Phusion polymerase is 1Kb/ 30 seconds. Thus the extension time of each and every PCR reaction is slightly different.
+
-
 
+
-
==Discussion==
+
-
After gel electrophoresis the correct band was found with the original primers, but no band was found with the new primers. We will proceed to gel extraction of the correct band tomorrow.

=Amplification of the parts for Subtilin Immunity BioBrick=
+
-
 
+
-
==Aim==
+
-
The aim of this experiment is to amplify the four parts for the Subtilin Immunity BioBrick using Phusion PCR again but using the original primers that were ordered and hydrated.
+
-
(Before this could be done, four of the primers, 1-T1_for, 2-T1_rev, 1-P1_for and 2-P2_rev, had to be re-hydrated.)

'''Table 2''': This table shows the four different Phusion PCR reactions that were carried out today. If this is successful, the four parts will be ligated together for the construction of subtilin immunity BioBrick with the help of Gibson Cloning method.

* The extension rate of the Phusion polymerase is 1 Kb/ 30 seconds. Thus the extension time of each and every PCR reaction is slightly different.
