Characterization of PLTs stored for up to 15 days in ISO and INT. (A) pH, (B) Lactate, (C) PLT Count. Aggregation response to (D) ADP and (E) Collagen and (F) Spontaneous Aggregation. ROTEM was performed and (G) MCF was reported. Flow cytometry was used to evaluate PLT activation markers including (H) Lactadherin (surface PS). Data are means±SEM. α p<0.05 vs Day 1-ISO, β p<0.05 vs Day 1-INT, * p<0.05 vs ISO (same day comparison).
