Every member in our team is trained by professors or instructors about the lab safety rules. We are also get tips about how to simplify some procedures and avoid mistake. In the lab, there are always teachers aside to help us. For example, when we were doing PCR and extracted the substrate. The instructors told us that the substrate must be keep in ice so that it won’t degrade. In addition, the instructors also told us some manners in the lab. For example, when entering a lab, people should dress lab-gown.
