Fig. 5. Work of de-adhesion of resting (open bars), PMA-stimulated (gray bars), Mg²⁺-treated (black bars) 3A9 cells bound to immobilized antibodies against LFA-1. The FD441.8 mAb recognizes an epitope formed by both and ß subunits of LFA-1. The M17/4.2 mAb recognizes an epitope on _L. The numbers given here were derived from measurements that were acquired with a compression force of 200 pN, 2 seconds contact and a cantilever retraction speed of 2 µm/second. The error bar is the standard error.
