Second, it is assumed that the mAb of interest can bind its specific antigen in a monovalent fashion only and this is by no means certain unless a monovalent antibody can be purchased. hsjs.src = "//cta-service-cms2.hubspot.com/cs/loader.js?pg=52ddbdc5-8c40-42de-ac95-c4d189751dda&pid=210093&hsutk=" + encodeURIComponent(c); The results are used to estimate detection limits for a prototypical imaging experiment. Otherwise I would recommend to include fluorescent beads to ensure the comparability of the measurements. WebThe mean fluorescence intensity is calculated by dividing the total fluorescence intensity by the bleb length. Subtract the baseline (background) signal from each samples mean fluorescence intensity. Our flow-cytometry lady always suggests to use median, especially if you don't have a nice Gaussian distribution of your cells. with a mean diameter of 15.1 m and a standard deviation of 5 m.
