Effects of interdomain hinge flexibility on flow-enhanced rolling. Microspheres bearing matched densities of L-selectin or L-selectinN138G were perfused through a flow chamber containing immobilized PSGL-1 (A, C, and E) or 6-sulfo-sLex (B, D, and F). Rolling parameters are presented as mean rolling velocities (A and B), mean stop time (C and D), or fractional stop time (E and F). The data in A and B represent the mean ± the SD from five experiments. The data in C–F represent analyses of thousands of rolling steps collected from 10–15 microspheres rolling for 1 s at each wall shear-stress for each pair of selectin–ligand interactions.
