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

Overview

This article describes a method for isolating washed platelets from human blood and measuring agonist-induced platelet aggregation using turbidimetry. The method is exemplified by studying the aggregation response of human platelets to collagen after pre-incubation with the Pannexin1 channel inhibitor Brilliant Blue FCF.
