Abstract
Summary
The uptake of the fluorescent dye euchrysine by human platelets is not affected by the aggregating agents ADP and adrenaline or by endotoxin, but is lost after exposure to anti-platelet and anti-red cell stroma serum. Granules of platelets fail to take up the dye at low temperatures and at an acid pH, both of these conditions being reversible. Platelets stored for 10 days at 5°C had normal staining of their granules.
