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.
