Representative light transmission aggregation traces of fresh platelet-rich plasma (A) and lyophilized platelet solution (B). The magnitude of platelet aggregation is recorded as % light transmittance. The light transmission percentage at 10 min was measured in response to adenosine diphosphate (10 µM)
