Serum-Red Cell Interactions at Low Ionic Strength: Erythrocyte Complement Coating and Hemolysis of Paroxysmal Nocturnal Hemoglobinuria Cells*

Jenkins, David E.

RESUMO

Complement coating and hemolysis were observed when erythrocytes from patients with paroxysmal nocturnal hemoglobinuria (PNH) were incubated in isotonic sucrose solution in the presence of small amounts of serum. Normal cells were likewise coated with complement components but did not hemolyze. Both normal and PNH erythrocytes reduced the hemolytic complement activity of the serum used in this reaction.
