Subtypes of i Demonstrated by the Use of Atypical Ii Cell Types and Inhibition Studies

摘要

Summary.Haemagglutination, absorption and elution studies with several anti‐i sera and atypical Ii red cell types and Ohcells were carried out and three subtypes of specificity were demonstrated. The fourth i subtype was demonstrated by an inhibition method using human scrum and amniotic fluid as a source of i substanc
