Revision as of 06:40, 3 October 2018
We are dedicated to following the safety and security rules of our university and the iGEM competition, as well as applicable state and national standards. As part of our project, we also investigated how our project might fit into local regulations which have more strict restrictions on biotechnology than the prevailing national standards. For more information regarding this, please see our Guide to Integrated Human Practices.
We have taken steps to design our experiment in such a way which minimizes risk and exposure to hazardous substances and cells by working in an appropriate setting, and being properly trained by safety officers at our university.
The threats posed by the CHO and AML cells are minimal. Both our cell lines have been categorized as non-infectious and non-toxic. Mammalian cells are optimized to live inside of mammals, and are not likely to survive in the natural environment or infect other mammals.
In order to prevent situations where the chassis organisms escape the lab, all members present in the lab space follow the safety regulations detailed by UC Davis. As an additional precaution all strains are sterilized via bleach (final concentration: 20%, 20 minute contact time) and/or autoclaving before disposal into the general garbage stream.
We used E. coli (non-pathogenic strain DH5α) to clone DNA. E. coli was not permitted to leave the lab and was sterilized via bleach (final concentration: 20%, 20 minute contact time) and/or autoclave prior to disposal.
