Figure 4From: Characterization of human platelet binding of recombinant T cell receptor ligandReal-time imaging of intracellular Ca2+in platelets. Platelets were loaded with the calcium reporter dye Oregon Green BAPTA 1-AM and imaged upon contact with RTL1000 or fibrinogen-coated surfaces. Graphs show the observed fluorescent intensity (arbitrary units) of a single platelet over the period of 6 minutes. The arrows indicate the platelets' arrival at the region of interest.Back to article page
