Abstract Recombinant D2.Gd (KdAdBbJbEbCbSbDb) was derived from parental strains B6 (H-2b) and DBA/2 H-2d). Recent peptide studies and 2-D electrophoresis studies from other laboratories have shown that the Aed (E beta) chain of D2.GD is structurally different from the parental-derived chain. An antiserum (D2.GD X A. TFR5)F1 anti-DBA/2 was produced that detects an Ia specificity (Ia.50) in the I-E molecule formed by the parent Aed chain and lacking in the I-E molecule formed by the variant Aed. chain. The variant Ae chain could have derived either from a mutational event or an intracistronic cross-over.
