Fluorocytometry
Flow cytometry (FC) is a technique used to detect and measure physical and chemical characteristics of a population of cells or particles. In this process, a sample containing cells or particles is suspended in a fluid and injected into the flow cytometer instrument. The sample is focused to ideally flow one … See more The first impedance-based flow cytometry device, using the Coulter principle, was disclosed in U.S. Patent 2,656,508, issued in 1953, to Wallace H. Coulter. Mack Fulwyler was the inventor of the forerunner to today's flow … See more Fluidics system of a flow cytometer Cells must pass uniformly through the center of focused laser beams to accurately measure optical properties of cells in any flow … See more Cell sorting is a method to purify cell populations based on the presence or absence of specific physical characteristics. In flow cytometers with sorting capabilities, the instrument detects cells using parameters including cell size, morphology, and … See more In addition to the ability to label and identify individual cells via fluorescent antibodies, cellular products such as cytokines, proteins, … See more Modern flow cytometers are able to analyze many thousands of particles per second, in "real time" and, if configured as cell sorters, can actively separate and isolate particles … See more Compensation Each fluorochrome has a broad fluorescence spectrum.

The composition of these two reagents effects a mild reaction with the blood cells, so that almost all of the blood cells’ structure remains intact. Thus, optimal separation is achieved, particularly of lymphocytes and monocytes.
