What is SSC A and FSC A?

forward scatter area (FSC-A) density plot can be used to exclude doublets as shown in Figure 3 below. A side scatter height (SSC-H) vs side scatter area (SSC-A) plot can also be used.

What does SSC measure?

Side-scattered light (SSC) is proportional to cell granularity or internal complexity. SSC is a measurement of mostly refracted and reflected light that occurs at any interface within the cell where there is a change in refractive index (Figure 3-1).

What is FSC W?

forward light scatter width (FSC-W) signal and the ratio of FSC area/peak. This change. in light scatter precedes the first cell division and may reflect blast transformation.

What is SSC flow cytometry?

side scatter
The light scatter is measured by two optical detectors. One detector measures scatter along the path of the laser (1). This parameter is referred to as forward scatter (FSC). The other detector measures scatter at a ninety degree angle relative to the laser (1). This parameter is called side scatter (SSC).

How do you analyze flow cytometry data?

Flow cytometry data analysis is built upon the principle of gating. Gates and regions are placed around populations of cells with common characteristics, usually forward scatter, side scatter and marker expression, to investigate and to quantify these populations of interest.

What are the 3 main components of flow cytometry?

The three main components of a flow cytometer are the fluidics, optics, and electronics (Figure 1).

What is granularity flow cytometry?

Cell Size and Granularity Using Flow Cytometry one can determine relative size of cells or events using a known control. Using the FSC and SSC parameters one can look at a mix of cells and distinguish them from one another based off of size and internal complexity. This gives a relative size for the cell.

How do I find my FSC number?

Visit the website portal of the Telangana National Food Security Cards. Select the option of ‘Reports’. Click on the ‘Ration Card Reports’ tab and then select the ‘FSC Card Status Report’ menu from the list of options given. Select your District and choose the respective shop number.

Can I draw gates around my cell type from the FSC-a plot?

It can be both difficult or easy to draw gates around your cell type of interest from the FSC-A x SSC-A plot. This is one of the reasons why a loose gate, compared to a tight gate, is recommended. For example, if you’re gating on whole blood, it’s fairly easy to identify your lymphocytes, monocytes, and granulocytes.

What type of gating should I draw for the SSC-a plot?

Gating on certain other tissues can be trickier, but at a minimum, it is often useful to draw a loose gate that excludes debris found at the very bottom left corner of the FSC-A/SSC-A plots.

Where do you find tight gates in FSC vs SSC?

They are often found at the bottom left corner of the FSC vs SSC density plot (Figure 2). When gating, bear in mind that blasting cells may be larger than resting cells; therefore, tight gates may mean you are missing a population that is important to your experiment.

Which scale presentation for leukocytes in FSC to SSC plot?

In FSC to SSC plots for leukocytes I would choose linear scale presentation. There is a unique pattern for leukocyte appearance in this plot. I attached a jpg with explanation of how leukocytes would appear hope it helps. Hi Javier. The choice of linear or log scales in flow cytometry comes down to the dynamic range needed to display your data.
