Abstract
Summary
Lyophilized human platelet material can be separated into thromboplastin-generating and heparin-antagonizing fractions. The heparin-antagonizing fraction does not, in itself, possess any thromboplastic activity but it reverses the effects of heparin on thromboplastin formation and thrombin activity. The material responsible is present in an aqueous extract of lipid-extracted platelets.
