The ice recrystallization inhibitor polyvinyl alcohol does not improve platelet cryopreservation.

PLT function was affected after cryopreservation with decreased PAC-1 binding in response to TRAP6 from 89% (±5%) before cryopreservation to 32% (±1) without and 29% (±4) with PVA after cryopreservation (Figs. Markers of PLT storage lesion were determined after cryopreservation of PC in the presence of DMSO without PVA (- PVA) or supplemented with 0.5 mg/mL PVA (+ PVA). [Extracted from the article]
