Day 1 [ 19/07 ]

• Learned how to safely use pipettes.

• Extraction of target plasmids.

• Amplification of fragments by PCR.  

• Agarose gel electrophoresis of fragments.

 

 

Day 2 [27/07]

• Cutting of the agarose gel and the extraction of the gel.

• Double enzyme digestion

• Formation of recombinant plasmids

 

 

Day 3  

• Preparation of LB solid culture medium from the liquid medium.  

• Transformed  the recombinant plasmids.  

  

 

Day   4  

• PCR identification of transformants

• Inoculate positive transformant seed solutions to LB culture medium plates.

• Processed the resulting pictures for the experiments (gel, petri dish with bacteria etc.)

  

 

Day   5-6  

• Expression of positive transformant containing plasmid A and C.  

• Prepared competent cell (BL21(DE3) containing plasmid B).  

• Transformed plasmid D to competent cell BL21 containing plasmid B.  

• Prepared SDS-PAGE gel.   

  

 

Day   7  

• Obtain cell lysate  by ultrasonic crushing machine.  

• Used Ni2+ column purification method to purify the cell lysate.  

• Used SDS-PAGE gel electrophoresis to identify protein samples.  

• Stained the gel after electrophoresis for observation.  

 

 

Day 8

• Isolated bacteria from E.coli and inoculated them to petri dishes.  

• Destained the SDS-PAGE gel.  

• In vitro cleavage of purified proteins.

• Proceeded with agar diffusion growth inhibition assay.  

 

Day 9

• Analyzed the results of the whole experiment

• Uploaded basic and composite parts to the iGEM website.

Day 10-11

• Proceeded with agar diffusion growth inhibition assay.

Day 12

• Prepare samples and sent to SubCat for agar diffusion growth inhibition assay.
