Measurement of protein–protein interactions via cell–cell binding assays. (A) CHO cells, either nontransfected (CHO) or expressing JAM-B or JAM-C, were labeled with either DiI or DiD molecular dye and mixed together in a 1:1 ratio. After incubation on ice for 60 min, the formation of doublets containing one cell of each type was evaluated by flow cytometry. (B) Results pooled from five experiments. Data represent means ± standard errors.
