The difference in cytosolic esterase-induced fluorescence with CMFDA between resting and activated human platelets.

<p>The activity of cytosolic esterase-induced fluorescence reaction is visualized with CMFDA. The fluorescence of resting platelets was clearly visible in laser confocal microscopy, whereas activated platelets release no or little fluorescence. A, C: Resting platelets; B, D: Activated platelets (activated by 100μM ADP); A, B: green fluorescence; C, D: bright field.
