Abstract excerpt
A Glanzmann thrombasthenia variant with a beta3 Ser752-->Pro cytoplasmic domain substitution has platelets that fail to aggregate or bind soluble fibrinogen (Fg) after activation. Despite this, Fg is normally present in the alpha-granules. We have used immunoelectron microscopy to examine the reactivity of Fg with the different pools of alphaIIbbeta3 in the patient's platelets. Immunogold labelling was performed...
