Scatterplots showing relative dimerization levels determined by single-molecule co-tracking for homodimerization and heterodimerization of IL-5Ra and βc in the absence and presence of IL-5, as depicted in (A)–(D). In the absence of IL-5,n= 28 for (E),n= 29 for (F),n= 25 for (G), andn= 20 for (H). In the presence of IL-5,n= 30 for (E),n= 33 for (F),n= 34 for (G), andn= 24 for (H).
