Studies on inhibitory reactions by antisera

Studies on Hemagglutination and Hemolysis by Escherichia Coli Antisera

A study on hemagglutination and hemolysis by Escherichia coli O111 and O55 (rabbit) antisera and on hemagglutination and hemolysis inhibition by E. coli O111 and O55 antigens revealed the following facts. 1. Red blood cells of man, dog, rabbit, guinea pig, sheep, rat, and chicken adsorb E. coli O111 and O55 antigens and thus become specifically agglutinable by the homologous E. coli antisera. 2...

Studies on Endothelial Reactions

1. Experimental cerebral and meningeal tubercles in the rabbit are formed from cells of endothelial origin. 2. These cells are derived apparently from other sources than the neighboring capillary endothelium alone. 3. The circulating macrophages, which, in this case, are capable of multiplying by mitosis while still free in the blood, are drawn upon in the formation of the cerebral tubercle. 4....

Immunochemical Studies of Antisera to Human

The immunochemical specificity of rabbit antisera to human fibrinopeptide-B (FPB) has been studied by comparing the relative abilities of FPB and of various proteins and peptides containing the NH2-terminal segment of the B/9chain of human fibrinogen to inhibit the binding of a radioiodinated FPB derivative by each of seven anti-FPB sera. Anti-FBP sera varied in the extent to which they cross-r...
