Due to the fact that of its imaging capabilities, the BD FACSDiscover ™ S8 Cell Sorter enables scientists to distinguish in between cells in various cell cycle phases.Flow cytometry is a single-cell analytical technique that uses fluorophore-labeled cell structures or biomarkers to separate between cell populations. Through this method, scientists detect the fluorescence intensity of several cellular biomarkers, in addition to the cells relative size and granularity. However, scientists can just utilize a restricted variety of fluorophores concurrently, as it can be difficult to compare fluorophores with overlapping emission spectra.Flow Cytometry VariationsTo increase its flexibility, researchers developed several circulation cytometry variations, including fluorescence-activated cell sorting (FACS), imaging circulation cytometry, and spectral flow cytometry. FACS is a technique that utilizes conventional circulation cytometry to determine cell populations with specific functions and enables the user to sort the chosen group into a collection vessel for additional propagation or analysis.1 This method enables researchers to separate a selected cell type from a heterogeneous sample, activated cells from non-activated cells, or cells revealing a specific protein from non-expressing cells.Imaging circulation cytometry is a technique that combines conventional flow cytometry with microscopy and permits the user to analyze a fluorophore-labeled cells fluorescence and morphology. In this method, the instrument lights up cells through filtered white light, producing brightfield conditions. Video cameras then catch both brightfield and fluorescent images. Like microscopy, imaging circulation cytometers permit researchers to determine a fluorophores extracellular and intracellular distribution. This technique also makes sure that cellular debris and cell clusters are not included in the analysis.2 Furthermore, imaging circulation cytometry is a high-throughput approach, so researchers analyze cells faster than microscopy-based imaging. Unlike conventional circulation cytometry, the brightfield images likewise let scientists figure out exact cell sizes instead of relative sizes.2 Spectral flow cytometry is a sophisticated variation of standard flow cytometry. In this approach, the instrument examines a fluorophores whole emission spectrum, instead of only a little portion, like traditional circulation cytometers.3 This makes it possible for spectral circulation cytometers to discriminate in between fluorophores with comparable emission spectra, which increases the number of fluorophores that scientists can use concurrently to separate cell populations. While scientists have actually previously integrated a few of these approaches, no instrument made use of all their benefits up until recently.
