Environmental microbes that disseminate during infection must adjust to disparate environments. As with all indirect measurements, a standard curve must first be created using calibration standards (for example, cytometric bead arrays), to establish the relationship between the fluorescence intensity measurements and the antibody binding to its target molecule. First, the beads measure binding of the mAb of interest via its Fc, which is determined by the affinity of the anti-Fc mAb on the beads. Since the acronym is ambiguous, we ask the scientist to specify if they are asking about median, mean, or geometric mean fluorescence intensity. Bookshelf This expression takes the Nth root of the product of N things: Median is the number which divides the first half of your data from the second half, if sorted by some variable. 5B). In reality, flow data is rarely normal and never perfect. MFI is often used without explanation, to abbreviate either arithmetic mean, geometric mean, or median fluorescence intensity. [Platelet alloimmunization in patients with oncologic blood disorders treated with multiple transfusions: prospective study in adults and children]. The median channel fluorescence value of a cell population can be resolved to a standardized fluorescence intensity by interpolation onto this straight line.
