Rupture-force histograms of fibrinogen-erythrocytes interactions.

<p>Rupture-force histograms from about 15,000 force measurements for each of the interactions between fibrinogen and young erythrocytes (blue), intermediate-aged erythrocytes (green) and old erythrocytes (red) subpopulations. All measurements were done with an applied force of 1 nN, pulling speed of 2 µm/s and loading rate of 4 nN/s. Gaussian peaks adjustment curves are shown in light green.
