This process of cell culture or tissue culture requires a method to dissociate the cells from the container and each other. Trypsin, an enzyme commonly found in the digestive tract, can be used to digest the proteins that facilitate adhesion to the container and between cells.his process of cell culture or tissue culture requires a method to dissociate the cells from the container and each other.

Using plasmids in the lab. Plasmids can be used as vectors to carry foreign DNA into a cell. Once inside the cell, the plasmid is copied by the host cellâs own DNA replication machinery. In the lab, plasmids are specifically designed so that the DNA they contain will be copied by bacteria.sing plasmids in the lab. Plasmids can be used as vectors to carry foreign DNA into a cell.
