Figure S1. In vitro function of talin-deficient platelets. (A) Static adhesion of platelets to type I acid-soluble collagen. Percent platelet adhesion was calculated as the number of adherent platelets relative to the total number of platelets seeded per well as described in Materials and methods. *, P < 0.05. (C) Aggregometry of platelets from Tln1fl/fl Cre+ and Tln1fl/fl Cre− mice stimulated with either 1 mM PAR4 peptide or 100 μM ADP.
