FIG. 1.

Flow cytometric analysis of RGD-dependent integrins expressed on mock- and β-transfected SW480 cells. Mock-transfected cells (SW480 mock) and cells transfected with wild-type β6 (SW480 αvβ6), wild-type β8 (SW480 αvβ8), or the chimeric β subunit β6/8 (SW480 αvβ6-8) or β8/6 (SW480 αvβ8-6) were incubated with (open histogram) or without (solid histogram) the indicated anti-integrin antibody, followed by an R-phycoerythrin-conjugated goat anti-mouse isotype-specific secondary antibody. The mean fluorescence intensity is shown for each antibody.
