An altered platelet granule glycoprotein in patients with essential thrombocythemia.


The protein profiles of washed platelets from nine patients with essential thrombocythemia were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. In four patients, an additional protein band (reduced Mr of 170,000) was clearly identified in both unstimulated platelet preparations and thrombin-released supernatant fractions. This band… (More)
