Immunofluorescence microscopy of DMSO-induced (A) and uninduced (B) LA7 cultures incubated with anti α₆β₁ integrin mAb. Cells reacting with the Ab are those forming domes (A). LA7 cells not involved in dome formation show scattered immunoreactivity (B). The secondary Ab used was fluorescein-conjugated anti-mouse IgG.
