Some cases … WebApr 8, 2024 · Platelet stimulation with collagen (1-30 μg/mL) in the presence of CaCl 2 led to relatively low [Ca 2+] i peak levels (Suppl. Fig. 1A i), not exceeding 9 ± 1% to 19 ± 1% of the peak levels obtained at 10 μg/mL CRP (Table 2). This is in agreement with earlier findings that collagen in platelet suspensions acts as a weak GPVI agonist [40].
