An improved method for dog leukocyte antigen 88 typing and two new major histocompatibility complex class I alleles,...

Development of preclinical dog models of solid organ and hematopoietic transplantation is critically dependent upon characterization of the polymorphic major histocompatibility complex class I and class II loci. While the class II alleles are easily typed as the polymorphic positions reside on a single exon, typing the class I locus is tedious. We have improved the class I typing method by designing improved primers and adopting alternative DNA amplification and cloning reagents that circumvent the use of radioactivity and the need for the single-stranded conformation polymorphism gels. The method is reliable in typing dogs for the class I dog leukocyte antigen (DLA)-88 locus, and through its use, we describe here two new alleles DLA-88*01101 and DLA-88*01201.
