Reading an EKG is done by careful viewing of the EKG strip. This  includes assessment of rhythm regularity, calculating heart rate,  observing the form of various parts of tâ¦he EKG and their timing.
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.

Cells like SF-9 and other insect cells are so sensitive that neither trypsin nor cell scraper can be used to detach them. Both of these methods damage the insect cells. These cells are detached by means of tapping the flask or by pipetting the medium over the cell monolayer. Where as most of the mammalian cells can be detached by trypsinization, scraping is a good option for cells which are sensitive to trypsin. Having said that researchers prefer to detach cells by scraper when the purpose of the experiment is to do western or enzyme assays.
