Flow Cytometric Analysis of Calcium Mobilization in Whole‐Blood Platelets

2003

Flow cytometry provides a convenient method to evaluate platelet activation by following the kinetics of intracellular free Ca2+, using sensitive fluorescent indicators that can be loaded into intact cells. Moreover, in the clinical setting, whole-blood techniques have obvious advantages to avoid artifactual platelet activation and allow the maintenance of near-physiological conditions. This unit describes a fast and sensitive flow cytometric procedure using the Ca2+-sensitive dye fluo-3 AM and the platelet-specific antibody CD41-PE to determine the kinetics of intracellular Ca2+ mobilization in whole-blood platelets with minimal manipulation of the samples. The technique may be applied to …
