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:

BBa_B0032

BBa_c0040

BBa_C0051

BBa_E0032

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
