["Sugar-agglutinability"].

Haemagglutination induced by saccharose is shown to go parallel with a binding of autologous isohaemagglutinin to the surface of erythrocytes. Under suitable conditions, i.e. in the presence of anorganic ions and health, haemagglutinin may be largely separated from the cell surface and the saccharose agglutination may be inhibited. Haemagglutination induced by saccharose will re-appear after agglutinins being re-adsorbed at low incubation temperatures and prolonged incubation time in non-ional as well as ional media. Therefore it is assumed that in the inert non-ional atmosphere the autologous haemagglutinin will produce a phenomenon of agglutination in non-homologous erythrocytes similar to that in homologous cells.

[Studies on the osmotic resistance and the viability of amidinated erythrocytes].

The present studies are concerned with properties of amidinated erythrocytes. The reactions of dimethyladipimidate with proteins in solution and red blood cells, respectively, result in an intermolecular cross-linking. Following an amidination of human serum albumin or human gamma-globulin cross-linked products of increased molecular weight have been demonstrated by polyacrylamide gel and immune electrophoresis. Human erythrocytes previously amidinated intensely, exhibit a restricted motility of membrane particles and cross-linked hemoglobin. Intensely amidinated erythrocytes are resistant against distilled water, and they do no longer agglutinate. The findings presumably indicate an increased permeability of the amidinated red cell membrane. The glycolytic activity was found to be normal in moderately amidinated erythrocytes. In comparison with normal red blood cells, previously moderately amidinated erythrocytes of the rat become sequestered more quickly after re-injection into the vascular system.
