WebFlow 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 cell at a time through a laser beam, where the light … WebOct 6, 2024 · Mean Fluorescent Intensity (MFI) is often used to compare expression of target of interest (TOI) across samples/ cell populations in …
WebOct 18, 2024 · The FACS is also graded on a scale of intensity, which gives a measure of how strongly the emotion is displayed. These measurements can also be synchronized with recordings of galvanic skin response, which provides a measure of arousal.

WebFlow cytometry is a numbers game. There are percentages of a population, fluorescence intensity measurements, sample averages, data normalization, and more. Many of these common calculations are useful, but surrounded by misconceptions. This primer will help you decide which calculation to use, when to use it, and how to interpret the results. 1.
