Ektacytometry of tg and wt erythrocytes. Tg erythrocytes (▪) were up to 3 times more elongable than wt erythrocytes (□) at shear rates that correspond to those found in the vasculature in vivo (about 11.5 s^–1 to 115 s^–1).⁴⁴  Moreover, enhanced elongation of tg erythrocytes was also observed at the maximal experimental shear rate (2500 s^–1) that can be applied without damaging the red cells. ** = P < .01 versus wt.
