Thromboplastin. I. Phospholipid Moiety of Thromboplastin.

Abstract

Phosphatidyl ethanolamine and phosphatidyl choline are inactive in the Thromboplastin Generation Test, but they become highly active when present with about 10% phosphatidyl serine. Phospholipids from fresh eggs are inactive, because they contain no phosphatidyl serine. Sodium deoxycholate gives clear, but less active or inhibitory suspensions.
