Safety
Overview
The CJUH-JLU-China team has always been committed to maintaining safety throughout the whole process of
research. To ensure the safety of the experiments, our team members have held in-depth discussions with safety
officers at every step of the project and continuously foresaw and avoided potential hazards. We have strictly
abided by laboratory safety regulations and specifically implemented a series of safety measures. This page will
introduce our efforts to ensure safety of the BreFast project in detail.
Staff
In late May, the members of the CJUH-JLU-China iGEM team underwent rigorous two-week laboratory safety training
and demonstrated their competence by successfully passing the safety test. Specifically, the experimental group
members received approval to work in cancer biology laboratories. Consistent with best practices, the team
adhered strictly to a policy that prohibits working alone in the laboratory, and instead ensured that
experiments were conducted under the supervision of safety officer Yueru Shi. This approach was designed to
effectively minimize the risks associated with handling hazardous materials, such as concentrated hydrochloric
acid, ethidium bromide nucleic acid dye, and ethanol.
Equipment
In the experiment, we handled biological materials with biosafety cabinets and chemical fume hoods.
Laboratory waste is properly disposed of in medical dustbins, glass bins or sharp containers. Flammable
chemicals are stored in controlled chemical cabinets away from fire sources.
We also placed fire extinguishers, hydrants, and first aid kits near the laboratory to prevent life-threatening
accidents
Reagent
Hazardous chemicals, such as hydrochloric acid, ethidium bromide, and ethanol, are securely stored in specially
designed containers. To ensure the safe handling of these chemicals, they are only used under the supervision of
the lab safety officer, Ms. Yueru Shi, and in the appropriate operating space.
It is of utmost importance that these chemicals are handled with care and precision, as they pose a significant
risk if mishandled. Therefore, all laboratory personnel must follow strict safety protocols when working with
these hazardous chemicals to minimize the risk to themselves and others.
Organism
Our project involves using a breast cancer screen system that does not involve any living organisms. This
ensures that our engineered organisms or their components cannot grow and spread in the environment, making them
safe for use in real-life applications. We used Escherichia coli Trans1-T1 for the bacterial strains, and MCF7
(human breast cancer cell), MBA-MD-231 (human breast cancer cell), and MCF10A (human normal mammary epithelial
cell) for the mammalian cell lines.
Summary
The CJUH-JLU-China team is dedicated to developing a breast cancer screen kit with the aim of benefiting
humankind. The project has carefully considered the safety of personnel, equipment, reagents, and organisms
throughout its course, and all experimental procedures have been executed in accordance with the Laboratory
Safety Code. This is a testament to our responsibility and accountability in ensuring a safe and secure
environment for all involved.
