Introduction

Like the fact that one chopstick is easy-break while ten chopsticks are hard to break off,iGEM is a team competition, which need not only cooperation in own team but also collaboration with other teams.This year,ZJU-China have worked with four teams tightly and participated many teamworks.

Take a look at our collaboration.

UCAS

UCAS is our important fellow iGEM team.We have established initial relationship as early as team building.We first participated in their questionnaire survey about security law problem raised by transgenosis technologies or related products, and we also helped them collect more than 70 samples in our university.

When we did molecular cloning experiments to build our BioBricks,it was difficult to build this part(BBa_K2207021) which has four repeated short sequences on its forepart.UCAS used Goldgate method to link 17 Oligonucleotides and successfully builded this BioBricks for us.We combined this part with mRFP to respond to the Calcium influx in yeast which is an upstream signal in our transduction system.

We further went two fishponds in Hangzhou,Zhejiang Province,to get water sample and did ion chromatography for supporting UCAS project’s great significance in aquiculture.

HFLS_H2Z_Hangzhou

We established mentorship with team HFLS_H2Z_Hangzhou at the very beginning. Since they are all new to igem, having little experience and very basic knowledge of the correct procedures and protocols they would require to complete their lab work, we gave advices on their team building, project design and experimental skills. Also, we helped them construct and standardize a gene that express a fusion protein of three different enzymes linked with EAAAK and GGGGS protein linker.

UESTC

We established the tight cooperation with UESTC after the pleasant communication in CCiC(Conference of China iGEMer Community). Since UESTC focus on the treatment of environment pollution, we assistance them to detect the TCP(trichlorophenol) remnant in soil by HPLC. Our graph of the result can help them to prove their achievement in the project.

We sent the sample of Trichoderma and the Phytophthora to their team, asking them to inoculate these fungi to the tissue culture Tobacco, a blank control is also needed. They took pictures of the different groups of tobacco three times a day. Their pictures indicate the benefits of our Trichoderma to plants and the bad effects of the Phytophthora clearly.

NEU-China

Our another partner was NEU-China,whose teammates had a leisure talk about projects with us in our laboratory in the end of the July.We later had collaborated in fluorescence detection tests.They used Microplate Reader to detect the EGFP expression in the hyphae of T.atroviride. Erenow we only observed the fluorescence by fluorescence microscope, the data they provided us were more quantitatively and measurable which proved that we have succeed in expressing heterogenous gene in our aiming chassis.

At the same time, We helped NEU-China to make a luminescence detection by stimulation of forskolin. Forskolin is a kind of adenylate cyclase activator widely used in improving the cAMP level in the cell.We found the fluorescence intensity of the sample added this substance was higher than control group, demonstrating that the reporter gene is available to respond to the activation of the cAMP pathway.
