Microelectrophoresis of Washed and Unwashed Human Blood Platelets, with Additional Studies of Platelets from Patients with von Willebrand’s Disease and Thrombasthenia^[*]

Summary

Microelectrophoretic mobility of washed platelets suspended in isotonic saline or citrated plasma was — 0.75 and — 1.03 (µ/sec.)/(volt/cm) respectively. Erythrocytes traveled about one-third faster. There was no difference between the mobility of unwashed and washed platelets. Mobility of platelets was normal in von Willebrand⁵s disease. Both mobility and isoelectric point were normal in thrombasthenia.
