Fig. 3. Lac behaves as a homophilic cell adhesion protein. Confocal microscopy
analysis of the bead aggregation assay. (A) Control or (B) Lachesin-Fc-coupled
beads were incubated in solution for 1 hour at room temperature and observed
under the confocal microscope for formation of bead clusters. Whereas control
beads do not form aggregates, Lachesin-Fc beads form large aggregates. Inset
(B) shows one aggregate at higher magnification.
