Difference between revisions of "Team:Tongji China/Safety"

All the members of Tongji-China have always attached great importance to bio-safety. We think we should introduce our adviser Lei Xue, a professor of genetics at the school of life sciences at Tongji University. His research areas include the molecular and genetic mechanism of tumorigenesis and apoptosis with drosophila model. Professor Xue and other researchers in the lab supervise us and give us a lot of guidance in fruit fly experiment.

In our project, we use 2 kinds of organism, Drosophila melanogaster and Escherichia coli . E.coli is ranked in the organisms of Level 1 risk goup. And because D.melanogaster is not included in the iGEM White List, we contacted Safety committee, Gender Diversity committee and Human Practices committee positively and got permissions.
Even though the E.coli and we work with is not harmful for the environment and health, we still assume that they may threaten the ecology, so we wear rubber gloves and lab coat when we do the experiments to keep it from direct touching with human body. We also do all the experiments with these living organism in the laminar flow bench to prevent those organism from getting into the outside air. After we do the experiments, we use NaClO solution to sterilizing waste such as the used agar plate and the used tips. What's more, everytime after we finish our work, we use UV light to sterilize the lab.

We attach great importance to the safety of Drosophila melanogaster experiments and learnt experimental operation earnestly in Xue's Lab. We have complete measures to prevent flies from escaping. After asking Xue's permission, we take photos to show how we keep the flies contained.


We use glass tube with cotton plug to keep the fruit flies in the lab and different samples are placed in different incubators with safety lock. In the process of culturing fruit flies, the fruit flies can not escape the incubator.
