Worthington Tissue Dissociation GuideMethods and Materials: Cell Release ProcedureIn order to transfer or pass cells in monolayer culture from one culture vessel to another it is necessary to release cells from the monolayer into suspension so that they can be easily handled by pipetting and diluting. Releasing cells from the monolayer is almost always accomplished with purified trypsin by a procedure known as trypsinization. A usual trypsinization procedure is detailed in the inset below.
Some researchers have found that procedures using crystalline trypsin can provide increased viability in cells after they are released. Viability is usually determined by measuring cloning efficiency, i.e., the ability of a single cell to attach to the wall of a culture vessel and divide to produce a colony of cells which is visible to the naked eye after staining.
