In transfusion medicine, platelets cannot be replaced by blood substitutes. Circulating platelets must respond quickly to changes in normal blood flow and blood-vessel injury to promote normal hemostasis. Adhesion of platelets at the site of vessel endothelial rupture is mediated through platelet membrane glycoprotein receptors. The integrity of these surface adhesion receptors and the signal-transduction pathways of activation will determine, in large part, how well a platelet functions in hemostasis. The deterioration of these systems during storage leads to a compromise of function known as the 'platelet-storage lesion'.

Purification of Platelets from Mouse Blood

Here, mouse blood was collected in the presence of an anti-coagulant. The platelets were purified by iohexol gradient medium using low speed centrifugation. The platelets were activated with thrombin to investigate if they were viable. The quality of the purified platelets was analyzed by flow cytometry and...

Turbidimetry on Human Washed Platelets: The Effect of the Pannexin1-inhibitor Brilliant Blue FCF on Collagen-induced Aggregation

We describe a straightforward method for the isolation of washed platelets from human blood followed by agonist-induced platelet aggregation measurements by turbidimetry. As an example we apply this method for studying the aggregation response of human platelets to collagen after a pre-incubation with the Pannexin1 channel inhibitor Brilliant Blue...
