==Aims==
+
-
The aim of this experiment is to run gel electrophoresis for the extracted and linearized plasmid pSB1C3 fragment which were amplified at 4 different melting temperatures by 4 separate PCR reactions and to put Ethidium Bromoide (EtBr) in the agarose gel instead of safeview die so as to get better resolution and brighter bands.

==Materials and Protocol==
+
-
Please refer to: [[Team:Newcastle/Gel electrophoresis| gel electrophoresis]] for gel electrophoresis protocol.
+
-
 
+
-
Please note that in this protocol we have made a minor modification which is that instead of adding 5µl of safeview dye, we have added 5µl of EtBr into the agarose gel so as to get better resolution and brighter bands.

'''Table 1''': Table represents 5 different Phusion PCR reactions for the amplification of linearized plasmid pSB1C3, so that it can be ligated together with other fragments for the construction of ''rocF'' with the help of Gibson Cloning method.
+
-
*For the 3rd PCR reaction where the melting temperature is set for 65°C, the number of cycles were increased to 35 instead of 29.
+
-
* The extension rate of the Phusion polymerase is 1Kb/ 30 seconds. Thus the extension time of each and every PCR reaction is slightly different.
+
-
* For learning about the ''rocF'' fragments, please refer to the [[Media:Cloning_strategy_for_rocF.pdf|Cloning strategy for ''rocF'']].

==Discussion==
+
-
All the 5 Phusion PCR reactions were done however, gel electrophoresis will be done tomorrow, to check whether the fragments have actually amplified or not.

-
 
+
-
==Conclusion==
+
-
Today afternoon, we would be running gel electrophoresis to check the outcome of the 5 PCR reactions and later all the fragments will be ligated with help of Gibson protocol if the fragments have amplified.

Overnight cultures for miniprep of filamentous cell part in pGFP-rrnB

Aim

The aim of this experiment is to set up cultures for minipreps to obtain stock of the filamentous cell part in pGFP-rrnB for transformation into Bacillus subtilis 168. We selected 12 colonies for screening.

Materials and Protocol

Please refer to growing an overnight culture.
