Assembly of endosomal detection operon

Task 1:
- Digest of isolate plasmids with ligated biobricks to verify the success of ligation
Methods:
- Digest of isolate plasmids using XbaI and PstI
- Reaction mixture composition: 0.5 μl purified plasmid DNA product, 0.5 μl XbaI (Fermentas),0.5 μl PstI (Fermentas), 2 μl Buffer Tango (Fermentas), 16.5 μl MQ water
- The reaction was performed three hours and it was subsequently inactivated via heating in 80°C for 20 minutes.
- In the next step reaction mixtures were loaded into the agarose gel to analize restriction pattern of the plasmids
Comment:
All isolated plasmids have not insert. The cloning must be performed another time
Task 2:
- Restriction digest of biobricks
Comment:
Due to obtain set of biobricks which each of them contain RBS and particular coding sequence some of biobricks were digested:
Methods:
- Digest of BBa_B0032 using SpeI and PstI
- Reaction mixture composition: 10 μl purified plasmid DNA product, 0.5 μl SpeI (Fermentas),1 μl PstI (Fermentas), 5 μl Buffer Tango (Fermentas), 34 μl MQ water
- Digest of other biobricks using PstI and XbaI
- Reaction mixture composition: 10 μl purified plasmid DNA product, 1 μl XbaI (Fermentas),1 μl PstI (Fermentas), 5 μl Buffer Tango (Fermentas), 34 μl MQ water
- Both reaction were performed approximately 7 hours they were subsequently inactivated via heating in 80°C for 20 minutes
Task 3:
- Ligations of biobricks
Methods:
- Ligation mixture composition: 8 μl digested plasmid with RBS, 9 μl digested CDS, 2 μl ligation buffer (Fermentas, PEG4000 have been added previously), 1 μl ligase T4 (Fermentas)
- Negative control mixture composition: 8 μl digested plasmid with RBS, 2 μl ligation buffer (Fermentas, PEG4000 have been added previously), 1 μl ligase T4 (Fermentas), 9 μl MQ water
- Duration of ligation was about 12 hours
Construction of K177012 operon1_part2
Ania
Tasks:
- Gel electrophoresis of the obtained clones.
- Repeat the ligation of the PcI and RBs.3LacI parts.
Results:
- Only small amount of DNA visible on the gel in 4 samples out of 20. Probably plasmid isolation has been done using too old solution 2. The visible DNA fragments are not the correct clone.
