Chapter 4: Data Analysis | Flow Cytometry - A Basic Introduction
Most instruments measure light scattered by the cells at right angles to the laser beam (side scatter, SS) and light scattered in a forward direction (forward scatter, FS) (see Chapter 2.3.1). The amount of light scattered is affected by the size, shape and optical homogeneity of the cells (or other particles being measured).
How to Interpret Flow Cytometry Data - Fortis Life
Histograms are used to graphically present single-parameter data. This type of data represents a single piece of information which, in flow cytometry, is often fluorescence intensity or forward scatter. The most common histograms in flow cytometry analyses display signal intensity on the x-axis and count on the y-axis.
Gating Strategies for Effective Flow Cytometry Data Analysis
Flow cytometry analysis is built upon the principle of gating. Gates and regions are placed around populations of cells with common characteristics, usually forward scatter (FSC), side scatter (SSC), and marker expression, to investigate and to quantify these populations of interest.

Scatterplot is sometimes called 2D histogram, which it is not. Cells scatter light when they pass through lasers beams. The level of light scattering in straight (forward) direction is proportionate to cell size. Cells also include granules, compartmented nuclei and other organelles. This leads to side scattering of light.

Single-Parameter or Univariate Histograms - Bio-Rad
These are histograms that display a single measurement parameter (relative fluorescence or light scatter intensity) on the x-axis and the number of events (cell count) on the y-axis. The data is expressed in a histogram which can be all the data collected or a selected (gated) population.
Light that is scattered in the forward direction after interacting with a particle, typically up to 20o offset from the laser beam's axis, is collected by a photomultiplier tube (PMT) or photodiode and is known as the forward scatter (FSC) channel.
Flow cytometry diagrams - Assay-Protocol
Lysed whole blood cell analysis is the most common application of gating, and depicts typical graphs for SSC (Side Scatter) versus FSC (Forward Scatter) when using large cell numbers. Normally, the signal of FSC (intensity of FSC light) is closely related to the size of single cell.
Antibodies 101: Reading a Flow Plot - Addgene
2024年2月6日 · As the gates progress from broadest markers to most specific, the first step is to separate cells from debris and roughly group the cells by size. This is done using side scatter (SSC) and forward scatter (FSC), which measure light that “scatters” past the cell, instead of fluorescent markers.
Forward scatter (FSC) and side scatter (SSC) are signals generated from the scattering or refraction of the laser light by the cell or particle being measured (a).
