Image color quantification (manual): This method involves visually assessing the intensity of the immunofluorescent staining in the predetermined regions of interest and assigning a numerical score to it. The median channel fluorescence of each fluorescent peak (not the unlabeled beads) was determined and plotted against the stated fluorescence intensity of each bead population as given by the manufacturers on a log-log display (Fig. The Table Editor should now have two entries, the MFI statistic and the No. Statistics in a,b,h were calculated using a two-tailed, unpaired Students t-test. })(); 28903 Avenue Paine Note: In the following example, we assume one bound antibody per molecule, which may not be true depending on antibody class, distance between molecules, and number of targeted epitopes on a given molecule. discover that the metabolic and epigenetic regulator PKM2 is expressed in the brain tissues from patients with Alzheimers disease and in patient-derived induced neurons. An alternative approach that is closer to absolute quantitation of binding sites for individual mAbs is use of the so-called "antigen-binding capacity" (or ABC) beads. This allows for the identification of unique cell populations or the tracking of expression changes within a population during differentiation.

For example, a large cell with more membrane and consequently more surface protein, can appear brighter than a smaller cell of the same type. Characterizing a bi-modal population: Any average only holds true for normal distributions, and a bi-modal population is by definition not normal. In most cases, when fluorescent signals derived from mAb binding are measured, the data are log-transformed to provide sufficient resolution of the cells.
