You cannot get an MFI for a double positive population per se. What you could do is first gate on one marker first (I always choose the marker that It is not possible to conclude that the CD69 expression is more dense on the NK cells, because there is no certain measurement of relative cell size; all that can be determined is that there are more CD69 molecules on the NK cells than their matched T cells. Nonetheless, such beads have been used to semiquantitate the expression of specific antigens on the surface of leukemic cells at the time of disease presentation and to then demonstrate that the level of expression of these antigens is specific to the malignant clone when compared with normal immature bone marrow mononuclear cells that arise in patients after chemotherapy (3). hsjs.src = "//cta-service-cms2.hubspot.com/cs/loader.js?pg=52ddbdc5-8c40-42de-ac95-c4d189751dda&pid=210093&hsutk=" + encodeURIComponent(c); In FCS Express, you may select three statistics to represent MFI for your data.
