Electron microscopic appearance of fibrin in thin sections.

Abstract

THE electron microscopic appearances of fibrin were first described by Hawn and Porter1 and Hall2, and these workers showed that in vitro fibrin had an axial periodicity of between 220 and 230 A. and a fibril width of approximately 150 A. Since that time, Levene3 and Still and Boult4 have investigated fibrin in pathological material and have shown that it possesses the same characters as artificially produced fibrin, and moreover seems to be bound in bundles which have a marked tendency to fold.
