We searched the DNA sequence of the PBANs from moths on NCBI, then contrasted to the amino sequences from papers so that we can selected the DNA fragments which directly correspond to gland-stimulating function, By ligating Ribosome binding site(B0034) and PBAN DNA sequence, we were able to make E.coli directly produce these PBANs instead of the original complex process of PBAN biosynthesis in insects. We had gotten nine kinds of PBANs,each of which is from one kind of moth
 
-
,after we constructed the PBAN biobricks, the B0034+BFP+J61048 biobrick was ligated behind the PBAN biobrick in order to model each PBAN biobrick respectively in the future and make observing the production of PBANs more convenient for us.

2.Before the commencement of our project,our team instructors and advisers have guided us to go through every expiriment to make sure everybody is well trained and fit for this project.
3.Everybody has to sterilize his/her hands and all the equipment platforms with alcohol solution(70%) before and after each expiriment.
4.Emergency equipments are well prepared and all the researchers understand how to use these equipments and their exact position.
5.It is not allowed that researcher carries experiment alone.There must be at least two members to conduct the experiment.
6.Food and beverages are not allowed to appear in the lab.

Public safety

1.All collected lab waste are sterilized, packaged and executed.

2.E.coli used in our lab is less competitive than wild type, because they are unable to form biofilms and to thrive in the intestine.

3.Liquid waste that contains E.coli is disinfected by adding peroxides and cleaners before it is disposed.


Instruments in our lab

1.incubator

The orbital shaker incubator is widely used in microbiology labs, cell biology labs, etc. It provides a stationary temperature to cultivate bacteria and cells. Some incubator also have functions to maintain the humility level. In our lab, the incubator is maintaining the temperature at 37 degrees Celsius, which is the optical temperature of E.coli growing. In this year, our team was authorized to work with an non-pathogenic bacterial strain, the Escherichia coli DH5. The strain ais regularly employed in research, industry and study. Biosafety Level 1 standard regulations were strictly followed while using these strains.
