Platelet activation and aggregation of cryopreserved PLTs. (A) The percentage of PLTs expressing activated integrin αIIbβ3 in response to stimulation with 32.5 μmol/L TRAP6 was determined by PAC‐1 binding in flow cytometry. (B) Maximal amplitude (%) of PLT aggregation in response to a mix of epinephrine, MeSADP, and TRAP6 is shown. AS‐PCT PLTs () were compared to standard (
) PLTs before storage (21°C) or after cryopreservation (−80°C; n = 8).
