Adhesion to collagen under flow is not affected by the G_i2α(G184S) mutation. Whole blood from G_i2α(+/G184S) mice and matched controls was anticoagulated with PPACK and perfused over collagen in a microfluidics flow chamber. After 297 seconds at 1000 seconds⁻¹, the shear was increased 10-fold to 10 000 seconds⁻¹. The data shown are the mean ± SEM from 7 G_i2α(+/G184S) mice and 8 matched controls (+/+).
