  2. Flow cytometry - Wikipedia

    en.wikipedia.org/wiki/Flow_cytometry

    Cell viability: Flow cytometry can be used as a cell viability assay by utilizing fluorescent dyes or markers that distinguish between live and dead cells. This parameter is critical in determining cell health and response to experimental or therapeutic settings. Viability of the cells in flow cytometry should be around 95% but not less than 90 ...

  3. Tetramer assay - Wikipedia

    en.wikipedia.org/wiki/Tetramer_assay

    The tetramers are labeled with a fluorophore, allowing tetramer-bound T-cells to be analyzed with flow cytometry. [4] Quantification and sorting of T-cells by flow cytometry enables researchers to investigate immune response to viral infection and vaccine administration as well as functionality of antigen-specific T-cells. [5]

  4. Naive T cell - Wikipedia

    en.wikipedia.org/wiki/Naive_T_cell

    In immunology, a naive T cell (T h 0 cell) is a T cell that has differentiated in the thymus, and successfully undergone the positive and negative processes of central selection in the thymus. Among these are the naive forms of helper T cells ( CD4 + ) and cytotoxic T cells ( CD8 + ).

  5. Immunostaining - Wikipedia

    en.wikipedia.org/wiki/Immunostaining

    Cells are immunostained in solution using methods similar to those used for immunofluorescence, and then analysed by flow cytometry. [citation needed] Flow cytometry has several advantages over IHC including: the ability to define distinct cell populations by their size and granularity; the capacity to gate out dead cells; improved sensitivity ...

  6. 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).

  7. T cell - Wikipedia

    en.wikipedia.org/wiki/T_cell

    T cells are one of the important types of white blood cells of the immune system and play a central role in the adaptive immune response. T cells can be distinguished from other lymphocytes by the presence of a T-cell receptor (TCR) on their cell surface. T cells are born from hematopoietic stem cells, [1] found in the bone marrow.

  8. Immunophenotyping - Wikipedia

    en.wikipedia.org/wiki/Immunophenotyping

    Immunophenotyping is a very common flow cytometry test in which fluorophore-conjugated antibodies are used as probes for staining target cells with high avidity and affinity. This technique allows rapid and easy phenotyping of each cell in a heterogeneous sample according to the presence or absence of a protein combination. [1]

  9. Cell sorting - Wikipedia

    en.wikipedia.org/wiki/Cell_sorting

    Flow cytometry cell-sorting yields very high specificity according to one or several surface markers, but one limitation is constituted by the number of cells that can be processed during a work day. For this reason pre-enrichment of the population of interest by immunomagnetic cell sorting is often considered, especially when the target cells ...
