	The Wistar Institute :: Flow Cytometry Facility (Site not responding. Last check: )
		Flow cytometry is a method, somewhat analogous to fluorescent microscopy, in which measurements are performed on particles (cells) in liquid suspension, which flow one at a time through a focused laser beam at rates up to several thousand particles per second.
		Practically all of the work done at the Wistar flow cytometry facility involves measuring the binding of a fluorochrome-labeled probe to cells and the comparison of the resultant fluorescence to the background fluorescence of unstained cells.
		The sister discipline of flow cytometry is flow sorting, in which the particles (cells) are separated and recovered from suspension based upon properties measured in flow.

	What Is Flow Cytometry
		As the labeled cells flow past a laser beam, the probes fluoresce, and the emitted light is directed to detectors which translate the light signals into information concerning the relative fluorescent intensity associated with each cell.
		Flow cytometry measures the percentage of cells in a population with each (or multiple) fluorescent probe(s) attached.
		The cell sorter is capable of sorting specific cell populations from a mixture of cells based on fluorescence profiles.

		Flow cytometry is a technology that allows a single cell to be measured for a variety of characteristics, determined by looking at how they flow in liquid [1].
		Flow cytometers make use of this technology by employing filters to block the original light source from reaching the detector, while the fluorescence emission is allowed through for detection, which allows only a very low background of stray light to reach the detector [2].
		In flow cytometry experiments, fluorescence is often achieved by the deliberate labeling of a cellular component using a fluorescent marker, usually a type of dye [3].

	Flow cytometry Summary
		Flow cytometry is a technique for counting, examining and sorting microscopic particles suspended in a stream of fluid.
		A flow cytometer is similar to a microscope, except it doesn't produce an image of the cell but offers high-throughput automated quantification of the set parameters for high number of single cells during each analysis session.
		In protein engineering, flow cytometry is used in conjunction with yeast display and bacterial display to identify cell surface-displayed protein variants with desired properties.

	Flow Cytometry Shared Service
		Flow cytometry is a powerful technique tailor made for making measurements on single cells.
		Once labeled, the cells are made to flow rapidly through the flow cell, or stream in air, where they are illuminated by a focused laser beam at a single wavelength (488 nm wavelength light from an argon laser).
		Some flow cytometers have the option for “sorting”, which by making the appropriate measurements, the computer makes the decision to sort or isolate a single cell by applying a charge to the cell just as it leaves the flow cell.
