Phosphatidylserine expression and MP formation in cold‐stored PLTs. (A) The percentage of PLTs binding annexin V was used as a measure for aminophospholipid expression. (B) MPs were defined as GPIbα‐positive events smaller than 0.9 μm (detection limit, 0.5 μm). The relative number of MPs to the total number of GPIbα‐positive events is depicted. AS‐PCT PLTs () were compared to standard (
) PLTs before storage (D2) and on D5 after 3 additional storage days at RT (21°C) or cold temperature (4°C; n = 6).
