Flow-FISH (fluorescence in-situ hybridization) is a cytogenetic technique to quantify the copy number of RNA or specific repetitive elements in genomic DNA of whole cell populations via the combination of flow cytometry with cytogenetic fluorescent in situ hybridization staining protocols. [1] [2] [3] Flow-FISH is most commonly used to quantify ...
Cell cycle analysis by DNA content measurement is a method that most frequently employs flow cytometry to distinguish cells in different phases of the cell cycle.Before analysis, the cells are usually permeabilised and treated with a fluorescent dye that stains DNA quantitatively, such as propidium iodide (PI) or 4,6-diamidino-2-phenylindole (DAPI).
7-AAD is also used as a cell viability stain. Cells with compromised membranes will stain with 7-AAD, while live cells with intact cell membranes will remain dark. Viability of the cells in flow cytometry should be around 95% but not less than 90%. [4] Flow cytometry using 7-AAD, wherein a lower signal indicates viable cells. Therefore, this ...
Flow cytometry (FC) is a technique used to detect and measure the physical and chemical characteristics of a population of cells or particles. [1] [2] [3] [4]In this process, a sample containing cells or particles is suspended in a fluid and injected into the flow cytometer instrument.
MHC pentamers have been used in the detection of antigen-specific CD8+ T cells in flow cytometry, [12] and are cited in over 750 peer reviewed publications , including several in the journals Nature [22] and Science. [23] [24] MHC pentamers can also be used in tissue staining, [25] and in magnetic isolation of antigen-specific T cells. [26]
The fluorochrome-based TUNEL assay applicable for flow cytometry, combining the detection of DNA strand breaks with respect to the cell cycle-phase position, was originally developed by Gorczyca et al. [4] Concurrently, the avidin-peroxidase labeling assay applicable for light absorption microscope was described by Gavrieli et al. [5] Since 1992 the TUNEL has become one of the main methods for ...

Flow cytometry using 7-Aminoactinomycin D (7-AAD), wherein a lower signal indicates viable cells. Therefore, this case shows good viability (viability of the cells in flow cytometry should be around 95% but not less than 90%. [8]). Cytolysis or membrane leakage: This category includes the lactate dehydrogenase assay. Assays such as these ...
