  3. 7-Aminoactinomycin D - Wikipedia

    en.wikipedia.org/wiki/7-aminoactinomycin_D

    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 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 ...

  5. Cell cycle analysis - Wikipedia

    en.wikipedia.org/wiki/Cell_cycle_analysis

    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).

  6. Flow-FISH - Wikipedia

    en.wikipedia.org/wiki/Flow-FISH

    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 ...

  7. Tetramer assay - Wikipedia

    en.wikipedia.org/wiki/Tetramer_assay

    A tetramer assay (also known as a tetramer stain) is a procedure that uses tetrameric proteins to detect and quantify T cells that are specific for a given antigen within a blood sample. [1] The tetramers used in the assay are made up of four major histocompatibility complex (MHC) molecules, which are found on the surface of most cells in the ...

  9. Immunostaining - Wikipedia

    en.wikipedia.org/wiki/Immunostaining

    Immunohistochemistry or IHC staining of tissue sections (or immunocytochemistry, which is the staining of cells), is perhaps the most commonly applied immunostaining technique. [2] While the first cases of IHC staining used fluorescent dyes (see immunofluorescence ), other non-fluorescent methods using enzymes such as peroxidase (see ...
