WebVideo: Passaging cells. This video explains why, when and how to passage cells grown in both adherent and suspension cultures. This includes cell dissociation, counting cells, determining optimal seeding density and preparing new culture vessels for passaged cells. All solutions and equipment that come in contact with the cells must be sterile. WebCell culture or tissue culture is the process by which cells are grown under controlled conditions, generally outside of their natural environment. ... Among the common manipulations carried out on culture cells are media changes, passaging cells, and transfecting cells.

WebTrypsinization is the process of cell dissociation using trypsin, a proteolytic enzyme which breaks down proteins, to dissociate adherent cells from the vessel in which they are being cultured. When added to a cell culture, trypsin breaks down the proteins that enable the cells to adhere to the vessel. Trypsinization is often used to pass cells ... WebSep 13, 2007 · A cell line is defined as a cell culture following its first passage 1.
