CHO cells in suspension. A cell suspension or suspension culture is a type of cell culture in which single cells or small aggregates of cells are allowed to function and multiply in an agitated growth medium, thus forming a suspension. Suspension culture is one of the two classical types of cell culture, the other being adherent culture. The ...
Dilution cloning or cloning by limiting dilution [1] [2] describes a procedure to obtain a monoclonal cell population starting from a polyclonal mass of cells. This is achieved by setting up a series of increasing dilutions of the parent (polyclonal) cell culture. A suspension of the parent cells is made. Appropriate dilutions are then made ...
Trypsinization 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 cell culture, trypsin breaks down the proteins that enable the cells to adhere to the vessel.
Cell culture is a fundamental component of tissue culture and tissue engineering, as it establishes the basics of growing and maintaining cells in vitro. The major application of human cell culture is in stem cell industry, where mesenchymal stem cells can be cultured and cryopreserved for future use. Tissue engineering potentially offers ...
Tissue culture flasks. RPMI 1640, simply known as RPMI medium, is a cell culture medium commonly used to culture mammalian cells. [1] RPMI 1640 was developed by George E. Moore, Robert E. Gerner, and H. Addison Franklin in 1966 at Roswell Park Comprehensive Cancer Center (formerly known as Roswell Park Memorial Institute), from where it derives its name. [2]
Cell synchronization is a process by which cells in a culture at different stages of the cell cycle are brought to the same phase. Cell synchrony is a vital process in the study of cells progressing through the cell cycle as it allows population-wide data to be collected rather than relying solely on single-cell experiments.
Cell suspension cultures such as tobacco BY-2 provide good model systems for these studies at the level of a single cell and its compartments because tobacco BY-2 cells behave very similarly to one another. The influence of neighbouring cells behavior is in the suspension is not as important as it would be in an intact plant.
In biology, a subculture is either a new cell culture or a microbiological culture made by transferring some or all cells from a previous culture to fresh growth medium. This action is called subculturing or passaging the cells. Subculturing is used to prolong the lifespan and/or increase the number of cells or microorganisms in the culture. [1]
