A New Genetic Marker of Human Immunoglobulins Determined by an Allele at the α2 Locus

摘要

Abstract.A new antigenic determinant occurring on human IgA2 protein is described. In family studies this marker showed to be dominant, non‐sex‐linked and antithetical to the first known marker of α2 chains. It is proposed to call this marker A2m(2), indicating that it is the second marker of IgA2 prot
