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.
