The invention discloses an application of a protein kinase A activator in blood platelet storage and a blood platelet storage method. From the embodiment of the invention, the invention discloses an application of the protein kinase A activator in inhibiting blood platelet apoptosis or keeping the activity of blood platelets for the first time under circumstance that the inducing and adjusting mechanisms of blood platelet apoptosis are unknown. The protein kinase A activator can inhibit afunction induced by blood platelet apoptosis and can prevent the blood platelets from being affected by apoptosis in storage and pathological stress conditions, so that the blood platelet survival time is prolonged. The method is a novel policy of improving the survival period of the blood platelets. The result verifies that determination of service life and survival of the blood platelets by regulating apoptosis has far-reaching significance in prolonging the storage time of the blood platelets, increasing the clinical application efficiency of the blood platelets and preventing the stored blood platelets from being rejected due to afunction of the blood platelets.
