title: An HLA-DR5 homozygous cell line expresses two DS (I-A-like) molecules.
abstract: Previous studies have indicated that LLA-DR homozygous cell lines express two DR molecules but only a single DS (I-A-like) molecule. This report demonstrates that an HLA-DR5 homozygous cell line expresses at least two distinct DS molecules. These two DS molecules are formed by the association of a single DS alpha chain with either of two DS beta chains. Four distinct Ia molecules have now been identified from this DR5 homozygous cell line.
