  2. Flow cytometry - Wikipedia

    en.wikipedia.org/wiki/Flow_cytometry

    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.

  3. Photoacoustic flow cytometry - Wikipedia

    en.wikipedia.org/wiki/Photoacoustic_flow_cytometry

    Furthermore, flow cytometry provides great ex-vivo analysis, but due to its pure optical source its penetration depth is limited making in-vivo analysis limited. Alternatively, photoacoustics may provide an advantage over flow cytometry as it receives an acoustic signal rather than an optical one and can penetrate to greater depths as discussed ...

  4. 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).

  5. Fluorescein isothiocyanate - Wikipedia

    en.wikipedia.org/wiki/Fluorescein_isothiocyanate

    Fluorescein isothiocyanate (FITC) is a derivative of fluorescein used in wide-ranging applications [1] [2] including flow cytometry.First described in 1942, [3] FITC is the original fluorescein molecule functionalized with an isothiocyanate reactive group (−N=C=S), replacing a hydrogen atom on the bottom ring of the structure.

    The first research study to report elevated organic fluorine levels in the blood of fluorochemical workers was published in 1980. [53] It established inhalation as a potential route of occupational PFAS exposure by reporting measurable levels of organic fluorine in air samples at the facility. [53]

  7. Cell synchronization - Wikipedia

    en.wikipedia.org/wiki/Cell_synchronization

    Flow cytometers can be used to collect multiparameter cytometry data, but cannot be used to separate or purify cells. Fluorescence-activated cell sorting (FACS) is a technique for sorting out the cells based on the differences that can be detected by light scatter (e.g. cell size) or fluorescence emission (by penetrated DNA, RNA, proteins or ...

    “The government knows what is happening,” Trump said of the drone sightings over many states, though he declined to say if he had been briefed by government officials on them.

  9. Droplet-based microfluidics - Wikipedia

    en.wikipedia.org/wiki/Droplet-based_Microfluidics

    The use of fluorescence detection techniques can be expanded into applications beyond data collection; a widely used method of cell and droplet sorting in microfluidics is fluorescence-activated sorting, where droplets are sorted into different channels or collection outlets based on their fluorescence intensity.
