Esco's Large BSC in Japan

Jun 13, 2017



In principle, cell sorting can refer to any technique that separates cells according to their properties. Both panning and magnetic cell sorting can be used for the selection of cells according to the expression of a surface molecule, because only such surface expressed molecules can be detected by these techniques using specific ligands. Both techniques also are bulk methods, which allow the rapid isolation of a large number of cells, however, without the ability to fine-grade according to expression level whereas they operate with a yes or no decision, unable to differentiate e.g. between low and high producing cells. Flow cytometry is the only method that allows both single cell selection as well as a (relative) quantification of the production of a specific compound. In addition, intracellular markers such as green fluorescent protein (GFP) or markers that describe a physiological activity, such as an enzyme activity or membrane potential, can only be measured and used for sorting by flow cytometry. Even though not a bulk method, desirable cells can be isolated quickly and efficiently with a traditional cell sorter one can easily look at a few million cells to find the rare outstanding performers (17 minutes at 1000 cells per second).
